Contents ofCrate
Each crate includes:
ACR.
Pole mounting bracket with clamps if
ordered. If a substation mounting bracketwas ordered it will be attached to the outside
of the crate.
Six connectors if ordered (15TP or 30TP).
caulking gun.
The appropriate mounting kit.
ADVC (which will normally contain two
batteries unless arrangements have beenmade to ship batteries separately).
Control cable.
On receipt, the contents should be checked forshipping damage and the manufacturer
informed immediately if any is found.
Ensure that the ADVC is stored
indoors until installation on site. If
storage outdoors is unavoidable,
ensure that the ADVC is kept in an
upright position.
UnpackingProcedure
Tools required:
Wrecking bar to remove nails.
Four D shackles, two slings and crane with asafe working load of 200kg to lift the ACR.
Screw Driver or Battery Drill with 8mm
socket.
16mm Spanner or Socket.
Procedure:
1 Remove top of crate and lift out the control
cable. Store carefully in a clean dry place.
2 Unscrew and remove the four (4) screws
located on the wall of the crate. The
mounting bracket, mounting kit and the two
pieces of wood that the screws have just
been removed from are all secured together.
Lift the complete mounting bracket out of the
crate.
Take great care not to drop thebracket, which weighs nearly 30kg
(66lb), onto the ACR.
3 Fit D-shackles to the lifting points on the
ACR and lift it out of the crate and on to theground using the crane.
4 Tip the crate on to its side.
5 Remove the bolts securing the ADVC and
slide the unit from the crate.
The control cubicle weighs
approximately 40 kg (88lb).
Control CableConnection
When installing or testing the ACR it is
necessary to connect and disconnect the control
cable either from the ACR, the ADVC or both.
The control cable is plugged into the base of the
ACR and the other end into the ADVC at the
bottom, right-most socket on the Control and
Protection Enclosure (CAPE).
To do this successfully requires the correct
technique:
Power down the control cubicle by switchingoff all MCBs. This should be done whenever
connecting or disconnecting the control cable.
To connect: hold the plug by the long sides,
check orientation, gently locate it on the socket
and push firmly home. Check it has locked by
wriggling the plug. If the plug cannot be
pushed on with moderate force then it has not
been located properly. Heavy force is never
required.
To disconnect: (1) Hold the plug by the short
sides and grip hard to release the clips inside
the plug (not visible). (2) Wriggle the plug to
allow the clips to release. (3) Then pull the plug
out.
Never pull the plug out by the
cable.
Testing &Configuring
The tests can be carried out on site or in the
workshop as preferred.
Unpack the crate as above and put the HV
cables, boots and the control cable in a clean
safe place where they will not be damaged or
soiled. Make a temporary earth connection
between the ADVC and the ACR. 1mm² copper
wire is adequate for the purpose.

Raise the ACR using a crane or forklift in order
to safely gain access to the bottom of the ACR.
Unbolt the cover plate over the switch cable
entry module (SCEM) on the bottom of the ACR
and connect the ACR end of the control cable to
the SCEM.
Lower the ACR on to props so that the control
cable is not damaged by being caught between
the base of the ACR and the floor.
Then connect the ADVC end of the cable to the
socket at the lower right-hand corner of theCAPE located inside the ADVC cubicle. (See
Site Procedure, Step 14. on page 3-3.)
The LV auxiliary supply (if applicable) should be
connected as shown in Figure 5 (page 3-5).
‘Turn on the battery and auxiliary supply circuit
breakers at the bottom of the control cubicle and
carry out the following tests:
1. Manual trip and close of the ACR.
2. Insulation test the high voltage connections
to earth to check for shipping damage on the
high voltage side of the ACR.
3. Configure the protection settings.
4. Perform primary current injection as
required.
5. Perform secondary current injection (if
required by your Authority) using a Test and
Training Set (TTS).
6. Fit and test a radio or modem if required.
7. Attend to the battery using the care
instructions given in “Battery Care” on
page 10-2.
Connecting the batteries with
reverse polarity will cause damage
to the electronic systems.
An application note detailing workshop and field
test procedures is available. Contact your agent
or distributor.
Transport toSite
If the unpacking and testing was carried out in
the workshop then the ACR and ADVC must be
transported safely to site. It is important the
following steps are carried out:
Turn off all ADVC MCBs and disconnect all
auxiliary power supplies. Disconnect the
control cable from both ACR and ADVC and
put back the cover plate on the bottom of the
ACR.
Transport the ACR, ADVC and all parts in a
safe and secure manner to site.
SiteInstallation
If you are replacing a pole-top control
cubicle (PTCC) with an ADVC, the
following should be considered:
The ADVC mounting points will be different1.
The connection to the auxiliary supply enters
the cubicle at a different point.
The earth stud is in a different position.
Accessory cables may need extending.
Unlike the PTCC which required an
auxiliary power supply rating of 50VA, the
ADVC requires 100VA.
If the auxiliary supply is provided by an
external VT connected through the ACR,
there are limitations to the supply ratings of
equipment that customers may fit. In ADVC,General Specifications See “Radio/Modem
Power Supply Continuous Current” on
page 11-4.
Unlike the PTCC, the ADVC has locking
hinges on the door which prevent the door
from swinging or blowing shut. When you
open the door to 180°, it locks into that
position. To close the door, disengage the
hinge locks by raising the door slightly
before rotating it.
Tools Required Torque wrench and metric socket set,normal engineers tools.
Tools to prepare pole as required.
Crane or other lift for ACR and ADVC, four D
shackles and slings.
Parts Required(Not supplied bythemanufacturer)
Two 20mm galvanised or stainless steel
bolts with washers and nuts etc. to bolt the
ACR mounting bracket to power pole. See
Figure 6 (page 3-6). If the optional pole
clamps have been purchased this is not
required.
Mounting parts for the ADVC. Either 20mmsteel strapping or 10mm galvanised or
stainless steel bolts, nuts, etc.
Fixing hardware for the control cable. This is
a 27mm (1 1/16”) diameter sheathed conduit
and can be fixed to the pole with ties, straps,
P-clips or saddles.
Earth wire and lugs for the earthing scheme
and parts for LV mains auxiliary power
connection. See Figure 5 (page 3-5),Figure 10 (page 3-10) and Figure 11
(page 3-11).
1. An accessory mounting bracket can be purchased to allow the use of the same mounting holes as were used with themanufacturer’s PTCC. (Part No. 99800125)

20mm sealing cable entry glands to suit
auxiliary supply mains cables, 16mm sealing
cable entry glands to suit antenna or
communications cable as required.
Antenna, antenna feeder cable, and surge
arrester as required if a radio is fitted (unless
supplied by the manufacturer).
Site Procedure To erect and test the ACR and ADVC, carry outthe following steps. Mounting details are given in
Figure 6 (page 3-6):1. Transport to site and carry out testing prior to
erection as required.
2. Connect cable tails and surge arresters
before raising the ACR. See "Surge Arrester
Mounting and Terminating" - page 3-4 .
3. Ensure that the pole is of sufficient strengthto support the ACR. A structural engineer
may be needed to calculate the stresses
involved.
4. Securely mount the ACR mounting bracketon the power pole.
5. Lift the ACR into position and lower it onto
the mounting bracket so that it sits on themounting bracket. See Figure 6 (page 3-6)
and Figure 8 (page 3-8).
6. Bolt the ACR to the mounting bracket with
the four 12mm nuts and bolts provided.
Tighten to 50 Nm.
7. Complete the high voltage connections.
8. Unbolt the SCEM compartment cover plate
from the bottom of the ACR. Connect the
control cable to plug P1 on the SCEM
located inside the ACR. Then bolt up the
cover.
See Figure 4 (page 3-1) for the correct way
to connect/disconnect the control cable.
9. Run the control cable from the ACR down to
the ADVC.
10. If the ADVC is to be bolted to the pole, drill
the top hole and fit the bolt. If it is to be
strapped, feed the straps through the slots
on the upper and lower mounting brackets.
11. Lift the ADVC into position and bolt or strap it
to the power pole.
Note that the
ADVC mounts
have key holes as
shown here, so
that you can lift
the ADVC on to
the mounting bolt
and slide it into position.
When mounting the ADVC to a
wooden pole, use a spirit level to
ensure correct alignment, andminimise torque on the mounting
brackets.
12. Attach the control cable to the power pole
maintaining maximum available separation
from the main earth bond (at 200mm for
wood and concrete poles and 150mm for
steel poles). Ensure that there is enough
cable available at each end to permit
connection to the equipment.
13. Run the earth connections as described in
“Earthing” on page 3-4.
It is vital that the earthing scheme
is carried out as described.
14. Push the control cable from the ACR through
the base of the ADVC
and then connect it to the switchgear socket
on the CAPE.
15. For LV mains supply run auxiliary wiring as
shown in Figure 10 (page 3-10). Make the
connection inside the ADVC as shown in
Figure 5 (page 3-5).
16. For LV supply from a dedicated transformer
supplied by the utility, connect as shown in
Figure 11 (page 3-11).17. For Integrated supply from an external
transformer, connect as shown in Figure 11
(page 3-11). (See also “Auxiliary Power from
Integrated Transformer” on page 3-5.)
18. Power down the ADVC by switching off allMCB’s. Note that this should be done
whenever connecting or disconnecting the
control cable from the ADVC.
19. Fit the batteries if they are not already inplace.
Fitting the batteries with reverse
polarity will cause damage to the
electronic systems.

Surge ArresterMounting andTerminating
The ACR is type tested for Impulse Withstand
Voltages up to 125kV depending on the model.
See "Ratings and Specifications" - page 11-1
When there is a possibility that lightning ornetwork switching conditions may produce peak
voltages in excess of 70% of the Impulse
Withstand Voltage, the manufacturer
recommends the use of suitably rated surge
arresters connected to each terminal of the
ACR.
The arresters should be mounted on the
mounting brackets supplied by the manufacturer
and earthed as described in Figure 7 (page 3-7)
and Figure 9 (page 3-9).
If the arresters are not mounted
close to the ACR the protection they
provide is significantly reduced.
Lightning induced damage to the ACR or ADVC
voids the warranty if surge arresters are not
fitted.
Mounting brackets are provided for surgearresters on the ACR. This is illustrated in
Figure 6 (page 3-6) and Figure 8 (page 3-8).
The surge arresters can be mounted on top of
the brackets or clamped to the side of the
brackets using the holes provided. Top holes are
12mm diameter, side holes are 16mm diameter.In this way most types of surge arrester can beaccommodated.
The user should check that phase/phase andphase/earth clearance will be sufficient for their
particular surge arresters and line voltages. For
some types of side clamping surge arresters,the phase/earth clearance may be insufficient at
the centre phase on the pole side at higher
voltages. In this case the surge arrester can be
mounted on the side of the power pole or an
increased clearance ACR mounting bracket
fitted.
Connections from the surge arresters to thecable tails can be made by stripping off the
cable tail insulation and using a parallel or “T”
type clamp to make the connection to the cable
tail. The connection should be made far enough
up the tail so that phase/phase and phase/earth
clearances are maintained. It is good practice totape the joint using a bitumen or mastic tape, to
maintain the cabling system insulation.
Earthing Figure 10 (page 3-10) shows the earthingcommon to all installations.
This arrangement earths the ACR frame and the
surge arresters directly to earth through a main
earth bond consisting of a copper conductor of
70 sq. mm. Any surges will flow down this path.
Do not earth surge arresters by a
different path, doing this may
cause damage to the control
electronics or ACR. Also, any
antenna should be bonded to the
ACR or the main earth bond .
The control cubicle is connected to this main
earth bond by a tee-off. The control cubicle
electronics are internally protected from
potential differences which may occur between
the ACR frame and control cubicle frame whilst
surge currents are flowing down the main earth
bond . No other connections to earth from the
control cubicle are allowed since surge currents
will also flow in those paths. Follow this
arrangement on both conducting and insulating
power poles.
Keep the main earth bond physically separated
from the control cable, as they run down the
power pole, by the maximum spacing available
and at least 150mm.
LV AuxiliaryPower fromMains
Where LV mains are connected to the control
cubicle to provide auxiliary power, the
connection must connect the neutral of the LV
system to a tee-off from the main earth bond as
shown in Figure 10 (page 3-10). A low voltage
surge arrester must also be fitted from the LV
phase connection to this tee-off.
This connection scheme bonds the LV and HV
earths and so protects the primary insulation of
the auxiliary supply transformer in the control
cubicle when surge currents are flowing. Fit
additional LV surge arresters to all the other LV
phases (if they exist), to balance the supply for
other users connected to the LV system.
If local conditions or wiring rules prohibit
bonding the HV and LV systems in this way,
providing the auxiliary supply to the control
cubicle from the LV mains system is not
possible. Instead, use one of the alternative
arrangements detailed below.

LV AuxiliaryPower fromDedicatedUtilityTransformer
Figure 11 (page 3-11) shows wiring and earthing
if a dedicated transformer is supplied by the
utility. Note that this should not be used to
supply any other equipment without consulting
the manufacturer to ensure that no hazard is
caused to the control cubicle electronics.
Figure 11 (page 3-11) shows that the
transformer and any steelwork is earthed to the
switchgear tank and that one side of the
transformer secondary is earthed to the earth
stud on the equipment panel inside the control
cubicle.
Auxiliary Powerfrom IntegratedTransformer
The manufacturer can provide a dedicated
voltage transformer outside the ACR tank which
connects directly into the control electronics.
This is called an Integrated Auxiliary Supply .
An external transformer is mounted on the pole
as shown in Figure 11 (page 3-11) which also
shows suggested HV connections. The
secondary of the external transformer connects
into the SCEM on the underside of the ACR. To
connect the transformer secondary, remove the
SCEM compartment cover plate, pass the cable
which is pre-fitted with a cable gland through the
hole, secure the gland, connect the auxiliary
supply to the screw terminal block on the SCEM
and replace the compartment cover.
No additional earthing for Integrated Auxiliary
Supply is required in addition to the common
earthing shown in Figure 10 (page 3-10).
If the secondary of the VT is
earthed, electronics damage willoccur.

4 Communications and Accessories Installation
Ensure that the ADVC is switched
off before proceeding with the
installation of any accessory.
Radio Antenna Mount the antenna and run the antenna feed to
the ADVC or run external communications cableto the ADVC. The communication cable/radio
antenna, enters the cubicle via the 16mm hole
provided on the underside of the cubicle.
Figure 12: Cable Entry
Protection ofRadioEquipment
It is highly advisable to connect a gas discharge
type of surge arrester in the antenna feed to the
radio. Failure to do so will result in loss of radio
and control electronics protection which could
lead to complete electronic failure due to
lightning activity.A failure of this nature is not covered
by the products general warranty
arrangements.
A feed-through or bulkhead type arrester fitted
to the bottom of the control cubicle is ideal. If
fitted internally the surge arrester should be
earthed to an equipment panel mounting stud by
the shortest possible wire. Holes are provided
for a bulkhead surge arrester.
If a surge arrester is not fitted then the co-axial
earth screen should be earthed to the
equipment panel by the shortest possible wire.

The CustomerCompartment
At the top of the customer equipment
compartment is an accessory mounting rail for
installing customer equipment and accessories.
Equipment installed in this compartment can be
powered from the terminal block also mounted
on the rail.
Connecting to
the TerminalBlock
Insert a 4 mm screwdriver or similar tool into the
square hole above the appropriate wiring point
on the terminal block. Angle the head of the
screwdriver slightly upwards and push it in, then
lever it downwards.
This action will correctly position the wiring
clamp so that the stripped end of the cable can
be inserted. Release and remove the
screwdriver then gently tug the inserted cable to
ensure that it is firmly gripped.
Radio/ModemPower
The battery-backed power supply for a radio/
modem is provided on the terminal block as
described above1. See Figure 13 (page 4-2) for
the correct radio connection point.
The radio/modem power supply voltage is set by
the user in System Status
RADIO - S: Radio Supply 12 Volts page. This isa password protected parameter.
If the auxiliary power fails, battery power can be
conserved by automatically shutting down the
radio/modem power supply. The shutdown takes
place after the radio holdup time, set in System
Status RADIO - S: Radio Hold 60 min. page bythe user, has elapsed. If the Radio Hold time is
set to zero then the radio supply will not
shutdown, except under special circumstances

IOEX2Installation
The Input Output Expander (IOEX2) module
provides optically isolated inputs and voltagefree outputs to allow connection to external
devices. It is installed in a die cast, sealed
enclosure which is mounted on, and earthed via,
the DIN rail in the customer enclosure as shownin the following picture: (See Appendix B for
IOEX2 dimensions.)
The IOEX2 is suspended from the DIN rail by
two fittings on its rear surface:
To fit the IOEX2:
1 Holding the IOEX2 perpendicular, place theupper hooks of the hanging fittings over the
top edge of the DIN rail.
2 Push the IOEX2 firmly against the back
surface of the Customer compartment until
the lower end of the hanging fittings engagewith the bottom edge of the DIN rail.
3 Push the green/yellow earth terminal firmly
on to the DIN rail until it is engaged at both
the top and bottom.
4 Connect the IOEX2 supply using the cable
provided to the terminal block connection
point as shown in Figure 13 (page 4-2).
5 Connect the communications cable to Port Bon the CAPE. This RS 232 port is assigned
by default to the IOEX2. Excess cable
should be run through the cable duct.
CommunicationPorts
The ADVC has numerous communications ports
available to the user:
Not all ports are available for use at the same
time. The ports can be enabled/disabled via
WSOS.
Permanently available ports are:
RS232 Port D Serial Port E (dedicated to the OCP)
10 base T Ethernet
Any 3 of the 5 following ports are available:

The ports typically have three uses:
WSOS communications
SCADA communications
IOEX communications
RS232 Four RS232 ports (A to D) are provided toconnect to conventional modems that providethe correct signalling for the communications
network used, e.g. optical fibre modem, or
telephone dial up modem, or RS232 radiomodem. All four ports have standard 9 pin D
male connectors and have the following pin
connections:
All RS-232 ports are not isolated from one
another or from the controller electronics. They
therefore can only be connected to devices
inside the controller that are powered by the
controller radio supply, including modems,
optical isolators, and radios.
Use of serial ports to connect
directly to other devices outside
the controller can cause damage
and void warranty. If connections
to other devices are required then isolation
interfaces MUST be used.
RS485 An RS485 port has been provided to enablehigher speed multi-drop connections that often
occur within substations. The RS-485 port is a
female RJ45 connector.

V23 FSK An in-built FSK modem provides half-duplexV23 signalling at 1200 bits per second. This
interface is primarily designed for use with voice
frequency radio systems and provides additional
signals for this purpose.
The V23 connector is RJ45:
The Push to Talk (PTT) signal is used to key up
a radio transmitter. PTT is implemented using a
Field Effect Transistor (FET) with an on
resistance of 3.3 ohm. When PTT is asserted
the transistor is turned on and connects the PTT
signal to 0V.
A busy signal can be provided by the radio to
indicate receive channel busy. High level is
+2.0V to +3.3V, and low level is 0V to +0.5V.The busy signal should be driven by an open
collector output or current limited to 10 mA.
Levels in excess of ±13V should
not be applied. The FET is rated for
a maximum of +32V and negative
voltages are not permitted.
Transmit and receive are unbalanced signals
relative to 0 volts and are not isolated. If a
DC level is imposed by the radio on the
transmit line then this should be less than
2.5 VDC.
If multiple ACRs are in use in a substation
application they can be connected to a singleradio using the 600ohm line isolator accessory
available from the manufacturer.
Ethernet The controller has a 10 base T Ethernet port.The port is a RJ45 female connector.
If the controller is connected to a
LAN or WAN then it is stronglyrecommended that:
1.Firewalls be used to limit user
access to the controller
2.Ethernet switches be used to
limit the volume of Ethernet data
reaching the controller's 10Base-T
port. (Use of Ethernet hubs is not
recommended.)
WindowsSwitchgearOperatingSystem(WSOS)
Windows Switchgear Operating System
(WSOS) is a software package available on a
PC that enables configuration, control and
monitoring of the controller.
The controller has its hatch port physically
connected to Port A via an interconnecting
cable. The default WSOS communications via
the port are 57600 baud, 8 bit, no parity, and 1
stop bit. WSOS communication set up
parameters are user configurable.

5 Testing Your Installation
The following sections give details of how the
ACR and ADVC, installed as described in
“Installation” on page 3-1, should be prepared
for operation.
Check that the installation and
external connections have been
carried out as described in this
manual and in accordance with
local regulations.
Ensure that earthing has been carried
out as described in “Earthing” on
page 3-4.
Check that no visible damage has occurred
during the installation.
Carry out any visual and electrical tests, such as
insulation and contact resistance, considerednecessary to prove that the installation is sound.
Powering Upthe ADVC
1 Turn on the battery circuit breaker,
The batteries are capable of
supplying very high currents.
Always turn off the battery circuit
breaker before connecting or
disconnecting the batteries in the cubicle.
Never leave flying leads connected to the
battery.
2 Turn on the auxiliary supply circuit breaker ifthe auxiliary supply is being provided by
either an LV mains or dedicated auxiliary
transformer.
3 Turn on the VT supply to cubicle circuit
breaker if the auxiliary supply is being
provided by an integrated transformer.
4 Powering up the ADVC with the ACR
connected will cause the ADVC to read data
from the ACR. This will take up to 60
seconds during which the message:
“READING - Do NOT disconnect
Switchgear” will flash at the top of thedisplay. The System OK LED on the OCP
should flash to indicate that the ADVC is
powered and functioning.
5 If the configuration file containing the
settings to be used in operation has notpreviously been loaded, it should be loaded
now using WSOS, or the settings should be
entered via the OCP.
The ACR and ADVC are now ready for
operation. Prior to energising the ACR, you
should perform the checks detailed below, to
confirm that the equipment is fully operational
and properly configured.If you are familiar with navigating
Operator Control Panel display
groups, proceed with the checks
described below. Otherwise, please
read the chapter, “Operator Control Panel” on
page 7-1 before continuing.
Battery For this and all subsequent tests youwill need to check settings on display
group pages (See “Display Groups” on
page 7-2.) You may also have to
check the Event Log (See “Event Log” on
page 8-1.)
1 In the System Status group, go to page
SWITCHGEAR STATUS - S2 Check the Battery status.
The battery may be in any one of four states:Normal; OFF; Low; High. At this point, the
battery state should be Normal with a
voltage within the range 23 to 29.5V.

Ensure the Aux Supply status is Normal. If
not, you cannot perform the remaining
battery checks at this stage.
3 Switch the battery circuit breaker off and
check that the battery status changes to
OFF. (Allow 3 - 5 seconds.)
4 Go to page EVENT LOG and check that
the bottom line of the display (the most
recent event) contains the Battery OFF
event.
When the battery status is Low Volts,
but the voltage is close to the normal
range lower limit, the battery will
charge up when the auxiliary supply is
turned on. If the voltage is very low, replace the
battery.
5 Switch the battery back on.
Connectionbetween theADVC and theACR
1 In the System Status group, go to page
SWITCHGEAR STATUS - S2 Check the Switch status.
It may be in either of two states: Connected
or Disconnected. “Connected” is the normal
state. If Switch is “Disconnected”, check the
control cable at both ends. If the status
remains “Disconnected”, the cable may be
faulty.
3 Check that the Switch Data status is Valid.
In normal operation, if Switch status is
“Connected”, Switch Data will be “Valid”.
If the control cable has been unplugged
(Switch “Disconnected”, Switch Data
“Invalid”) then re-plugged (Switch status
“Connected”), the Switch Data status will
remain “Invalid” during the time taken to read
switch data from the SCEM, and a message
to that effect is displayed.
If Switch Data remains “Invalid”, check the
following:
Examine each end of the control cable,
checking for bent or broken pins and rectify if
found. Also check the socket at both the
SCEM and P1 in the ADVC for damage.
If the pins are OK, the cable itself may be
faulty1, therefore test the control cable for
continuity.
If Switch Data remains “Invalid”, check the
power supply to the SCEM by checking the
voltage on Pins 2 and 5 of the control cable.
The voltage should be approximately 36VDC
if the auxiliary supply is present or
approximately 26VDC if running on
batteries.
AuxiliarySupply
1 In the System Status group, go to page
SWITCHGEAR STATUS - S2 Check the Aux Supply status.
The auxiliary supply may be in either of two
states: Normal or Fail.Ensure the battery status is Normal.
3 If using LV auxiliary supply, switch the
auxiliary supply off, OR if using integrated
auxiliary supply and the VT is energised,
switch off the VT supply to cubicle circuit
breaker. Check that the Aux Supply status
changes to Fail. (Allow 3 - 5 seconds.)
4 Check that the battery voltage has dropped
by approximately 2V, and that the battery
remains in Normal state.
If the battery voltage continues
dropping, and the battery state is
LOW, the batteries may be flat. If
the batteries are flat, replace
them.
5 Go to page
EVENT LOG and check that
the bottom line of the display (the most
recent event) contains the Aux Supply Off
event.
6 Switch the auxiliary supply back on.

The tag has two possible settings: Applied or
OFF. OFF is the default.
4 Press the SELECT key to select the work tag
field.
5 Press to change the setting to Appliedand then press ENTER to activate the setting.
The message: “WORK TAG APPLIED” will
flash at the top of the display.

event.
7 Return to page
SWITCHGEAR STATUS - S and change thesetting back to OFF.
TerminalDesignationand PhaseRotation
The power system phase assigned to each set
of bushings on the ACR must be correctly
indicated at the time of installation of the ADVC.
This process is called “setting the phasing”.
Setting the phasing affects all the displays,
events, etc., concerned with recloser terminals,
for example: voltage measurements, live/dead
terminal displays and maximum current events.
Normal/default phasing is A, B and C for
bushings I + X, II + XX and III + XXX. Normal/
default phase rotation is ABC.
If the phasing at the ACR and/or phase rotation
of the network are different from the default, you
must set the phasing and/or the phase rotation.
Phasing is set from the System Status page
TERMINAL DESIGNATION/ROTATION - S
1 Press the SELECT key to select the Phasing
field.
2 Press to change the setting.
3 Press the ENTER key when you have the
required phase combination. The controller
then orientates the currents and voltages to
match the selection.
4 In the Phasing field, select the phase
rotation - either ABC or ACB.
5 Go to page EVENT LOG and check thatthe bottom line of the display (the most
recent event) contains the Phasing order
event.
6 After the phasing has been set, you should
record the details on the label on the rear of
the control cubicle door (above the operator
panel) to indicate the relationship between
the bushings and phases.
Power FlowDirectionSetting
The ACR is a symmetrical device meaning that
either side can be connected to the power
source. However, the power source would
normally be connected to the side with the
CVTs. The bushings on that side are labelled l,
ll, and lll.
Consequently, after installation, the controller
must be configured to designate the source
side.
The power flow direction is configured on page
SYSTEM STATUS - PHASE VOLTAGE and POWERFLOW:
and may be either
Source I, Load X or Source X, Load I.
When changed, this reverses the power flow
direction but not the phasing.
Power flow direction setting is used to
determine:
Whether the source or load corresponds to
(I) or (X) on the voltage measurementdisplays.
Which direction is positive power flow for useon the kWh totals in the Maximum Weekly
Demand display and APGS.
Which is the source or load for Live Load
Blocking. Which is the source or load for Directional
Blocking/Protection.
Tripping andClosing
If system conditions allow, tripping or closing
can be carried out at this point.
1 Trip and close the ACR from the ADVC. See
“Operator Control Panel” on page 7-1. for
information on the Trip and Close controls.
2 Tripping and closing should cause the LED
on the appropriate TRIP/CLOSE button to
illuminate which should agree with the
position of the pointer on the ACR.
Enable/DisableSwitches
For each of the CLOSE and TRIP keys in turn, test
ENABLE and DISABLE by:
1 Disable either mechanism e.g. CLOSE.
When the CLOSE or TRIP mechanism
is disabled, the message

2 Go to page EVENT LOG and check thatthe bottom line of the display (the most
recent event) contains the Close Coil Isolate
event. (For the same test of the TRIP
mechanism the Event Log should display
Trip Coil Isolate.)
3 With both mechanisms disabled, check that
pressing each of the CLOSE and TRIP keys
is ineffective.
4 Enable both CLOSE and TRIP mechanisms.
MechanicalTrip
1 Use a hook stick to manually trip the ACR
via the manual trip lever.
2 Go to page EVENT LOG and check thatthe bottom line of the display (the mostrecent event) contains the Mechanical Trip
event.
SecondaryInjectionTesting
If secondary injection testing is required to test
protection settings but operation of the ACR is
not possible, secondary injection can be
performed with a suitable current injection set
with the Test and Training Set (TTS) in
standalone mode connected to the ADVC, andthe ACR disconnected.
If tripping and closing of the ACR is possible and
preferred, perform secondary injection testing
with the TTS in parallel mode.
Any secondary injection must use a
frequency which corresponds to the
frequency set in the controller.
PrimaryInjectionTesting
If the ACR can be isolated from the network,
primary injection testing can be performed if
required.
Power FlowDirectionTesting
This test is to ensure that the source and load
designations are correct.
This test is valid only if the ACR is
being supplied from a single sourceand can be energised before closing.
Since either side of the recloser can be
connected to the power source, the controller
must be configured to designate the source
side.
The power flow direction is configured in System
Status on the PHASE VOLTAGE and POWERFLOW - S page.
If the I -side bushings are connected to the
source, the setting should be Source I,
Load X.1 Display the page and check the Source,
Load configuration.
The correct power flow setting can be confirmed
by energising the ACR while it is open.
2 With the recloser energized but still open, in
System Measurement, go to SOURCESIDE VOLTAGES - M
3 Check the source side voltages - eitherphase to earth (ground) or phase to phase
e.g.

Control Electronics Operation

6 Control Electronics Operation
The ADVC is purposely designed for outdoor
pole mounted operation. The cubicle is vented
and insulated to minimise internal temperature
variation and maximise battery life.
Figure 24 (page B-2) shows the cubicle’s
dimensions.
Sealing &CondensationAll cubicle vents are screened against verminentry and the cubicle door is sealed with
replaceable foam tape.
Complete sealing against water entry under all
conditions is not expected e.g. during operation
in the rain. Instead, the design is such that if any
water does enter, it will run out of the bottom
without affecting the electrical or electronic
parts. The extensive use of stainless steel and
other corrosion proof materials ensures that the
presence of moisture has no detrimental effects.
Condensation can be expected to form undersome atmospheric conditions such as tropical
storms. However, condensation will be on metal
surfaces where it is of no consequence. The
water runs out in the same way as any other
water entering the cubicle. Condensation will
run out of the bottom or be dried by ventilation
and self heating.
All electronic modules are fully sealed and have
self heating.
AuxiliaryPower Source
The auxiliary supply is used to maintain charge
on the sealed lead-acid batteries that provide
standby power when auxiliary power is lost. The
controller monitors the status of both the
auxiliary and battery supplies.
A low power mode is activated when the
batteries are nearly exhausted due to loss of the
auxiliary supply. This mode minimises power
consumption while still maintaining basic
functionality.
Controller The controller comprises 3 modules (SeeFigure 18 (page 6-3):
Power supply unit (PSU)
Control and protection enclosure (CAPE)
Basic Display Unit (BDU).
The ADVC block diagram is given in Figure 19
(page 6-4).
PSU Module The PSU module supplies power to the CAPE,and to the customer compartment. The PSU
module:
connects to the batteries
controls the supply from external auxiliary
sources
filters these supplies and manages the
battery power level.
It also performs battery testing and has a non-
volatile, real time clock. A general purpose
power outlet is available as an optional extra
(country customizable). The incoming power is
protected and isolated by a circuit breaker. The
supply from the batteries is protected and
isolated by a circuit breaker.
The electronic components are contained inside
a housing that provides environmental
protection, sealing and EMI shielding. The
power outlet, circuit breakers and switches are
easily accessible when the ADVC door is
opened. The batteries are located and retained
on the exterior top of the PSU module.
CAPE Module The CAPE Module comprises two printed circuitboard assemblies and the trip and close
capacitors housed in a die-cast aluminium
enclosure. The two printed circuit board
assemblies are:
PCOM: Protection and Communication
Module
SWGM: Switchgear Module
The CAPE enclosure is manufactured from
pressure die-cast aluminium. The front surface
with the user and switchgear connectors, andthe rear surface, are gasketed to provide an
IP65 Degree of Protection. The enclosure also
provides EMC shielding for the CAPE
electronics.
The PCOM is the heart of the ADVC and
includes the data acquisition hardware
(including a powerful Digital Signal Processor)
and communications hardware (Ethernet,
RS232, RS485 and V23). All user-interface,
measurement, protection, communication andcontrol functionality is provided by software
running on the PCOM.
The SWGM contains the switchgear interface
hardware, SCEM interface hardware, EMCprotection and filtering devices and high voltage
inverters for the trip and close capacitors.

Event Log
8-1
8 Event Log
When the status of the control electronics or
switchgear changes, events are generated
which are recorded in an Event Log for display
to the operator. Examples of such events are
‘Load Supply On’ or ‘Lockout’.
Events are viewed on the Event Log pages and
can also be up-loaded and viewed with the
Windows Switchgear Operating System.
The event log display looks like this:
Events are dated, time stamped, and displayed
in the order in which they occurred.
The key scrolls the display downward toshow older events, the key scrolls thedisplay upward to show more recent events.
Pressing the key removes the title of thedisplay to make more room for events. The title
will only be restored when the event log is
selected again from the top level menu.
Display
Updating
The event log display will update automatically
with new events, provided the most recent eventis on the bottom line of the screen. When new
events occur they are entered at the bottom of
the screen and the older events are scrolled up.
Event LogFormat
Each event occupies one line of the event log.
The standard display contains (reading from the
left):
the date of the event,
the time of the event, and
the event description.
Additional information e.g. event source isrecorded and can be made visible if you press
the ALT key while the event is displayed.
Using the ALTKey
If the Alt key is pressed whilst the event log is on
display, the date and time details may bereplaced with extra information that includes, at
far left, the event source and followed by, if
applicable, additional event details. Examples of
source codes are:
Additional event details are available where the
combination of the source plus event descriptionalone will not precisely identify the event e.g.
protection events or events sourced to WSOS.
Examples of additional details are:
the protection group
curve
trip number
port identification
protocol.
Typical EventLog Displays
A typical sequence of events for a phase/phase
fault, which had instantaneous protection on the
first trip and inverse time protection on the
second trip, with two trips to lockout might be as
shown in Figure 21 (page 8-2).
However, if the fault was cleared after the first
trip has occurred, the controller will generate a
‘Sequence Reset’ event once the Sequence
Reset Time has expired, as shown in Figure 22(page 8-2).

9 Power System Measurements
The current transformer (CT) signals and
voltage screen (CVT) signals from the recloser
are digitised by the ADVC and used to provide a
variety of data for the operator.
The ADVC measures up to 10 power system
components:
A, B, C, phase and spill currents, phase-earth voltage on all six terminals.
The ADVC uses the above measurements to
derive many system measurements including:
frequency,
phase to phase voltages,
total and per phase power (kW, kVA, kVAR),
total and per phase power factor,
harmonics,
earth current, and
sequence components.
In addition the ADVC also measures severalinternal values such as:
CAPE temperature,
switchgear temperature1
auxiliary voltage,
battery voltage.
Power SystemFrequency
The controller must be set for the correct power
system frequency – either 50 or 60 Hz.
This is set on page

Maintenance
10-1
10 Maintenance
Maintenance can be carried out using standard
electricians’ and mechanics’ tools.
Be careful to ensure that if working
on the ADVC with the door open in
heavy rain, water does not enter
the circuit breakers or general
power outlet.
ACRMaintenance
No user maintenance of the ACR mechanism isrequired.
The ACR should be returned to the
manufacturer for refurbishment if the
mechanical duty or breaking duty is exceeded.
This is checked by examining the remaining
contact life on the Operator Control Panel.
When the remaining contact life in any phase
approaches zero, the ACR has reached the end
of its life and must be replaced.
A warning is displayed in the event logwhen the remaining contact life reaches
20%.
Every five years the bushing boots should be
checked, cleaned if necessary and the pointer
checked to ensure it is free from mechanical
obstructions. In areas of high atmospheric
pollution more frequent cleaning may be
appropriate.
ADVCMaintenance
Maintenance of the ADVC is required every fiveyears. The manufacturer recommends the workdescribed below.
Cleaning Check for excessive dirt on the cubicle,particularly the roof, and clean off.
Ensure that the mesh covering the air vents and
the water drainage holes in the base are clean.
BatteryReplacement
Battery replacement is recommended after a
period of five years. See "Battery Care" -
page 10-2 .
The procedure is:
1 Turn off the battery circuit breaker.
2 Unplug batteries and replace with new
batteries.
Ensure that battery polarity is
correct.
3 Turn on the battery circuit breaker and
ensure that “Battery Normal status”, is
restored on the page

Door Seal Check the door sealing rubber for perishing orundue hardening. If necessary renew the seal.
Battery Care The battery is predicted to provide goodperformance for the recommended five year
service period. This is based on the battery
manufacturer's data. No battery warranty isgiven by the manufacturer of the ADVC.
Once in service, batteries need little care.
Procedures for storage and other contingencies
are as follows:
Batteries should be stored at a temperature
of between 0°C to 30°C (32°F to 86°F) and
cycled every six months. Batteries should be
stored for a maximum of one year.
Batteries should be cycled prior to putting
into service if they have not been cycled
within three months. When shipped by the
manufacturer the batteries will have been
cycled within the previous 30 days.
If the batteries become exhausted in service
and are left for more than two weeks without
auxiliary supply being restored to the ADVC
they should be taken out, cycled and have
their capacity checked before being returned
to service.
To cycle a battery, discharge with a 10 Ohm 15Watt resistor to a terminal voltage of 10V. Next,
recharge it with a voltage regulated DC supply
set to 13.8V. A 3A current limited supply is
appropriate.
Battery type, either standard or extended
temperature, is given in Appendix A (page A-1).
More information on the battery care is available
from the battery manufacturer.
These batteries are capable of
supplying very high currents.
Always turn off the battery circuit
breaker before connecting or
disconnecting the batteries in the cubicle.
Never leave flying leads connected to the
battery.
