ARTES 400 II INTRODUCTION 5

1 IntroductionThe ARTES 400 II test system is used for carrying out general operating tests and for testing

the configured excitation and tripping characteristics of various protection devices, such asdistance protection relays, overcurrent relays, voltage and frequency relays, for example. In

addition, power, voltage, current and frequency transducers can also be tested with ARTES400 II and the test instrument can also be used as a three-phase function generator which isfreely configurable with regard to amplitude, frequency and phase relation.

ARTES 400 II has three voltage and six current signal sources with a very high output power.This makes it possible to test electromechanical relays and differential protection relays usinga test set only, without additional equipment.

In addition to static tests, dynamic tests can also be carried out during which current,voltage, frequency and phase angle can be varied within wide ranges. It is also possible to

address the protection device to be tested with binary signals as well as with analogmeasured quantities.

The reaction of the device under test is measured in real time synchronously to the signalgeneration process and is evaluated directly. In addition to the binary measurement inputs,

ARTES 400 II also has eight analog measurement inputs which make it possible to recordcurrents and voltages (disturbance recorder function). During tests these recordings can thenbe "played back" via the hardware as transient waveforms.

ARTES 400 II has been especially developed for transport and operation in adverseconditions. A high degree of system integration has lead to a compact design in a portable19" test case (3HU).

Apart from the ON/OFF switch, no operating elements are located on the test instrumentitself. The test system is operated and controlled via the ARTES software using a standardPC. The programme and its operation are described in the ARTES User Manual, while

information regarding the test instrument itself, or rather the "hardware" and how to connecta test object, can be found in the following pages of the present operating instructions.

ARTES 400 II COMMISSIONING 7

3 CommissioningARTES 400 II should only be used in dry surroundings. Damp and wetness can damage the

test instrument.

WARNINGThe test instrument should never be used in a location which is subject to explosion hazards.

3.1 Setting upWhen the test instrument is brought from a cold environment into a warm one, condensation

can result in dangerous situations. For this reason, it is important that earthing instructionsare followed exactly.

Internal fans protect the test system from overheating. Ventilation is carried out via aventilation grid located on the underside of the test instrument. To prevent dirt particles fromentering the test instrument, the ventilation grid is lined from within by a dust filter.

Before commissioning the test instrument it is important to ensure that this filter is not dirty.If it is dirty, the test instrument must not be operated. Contact the manufacturer or a servicepartner in this case.

Several air outlets are located on the back panel of the housing (figure 1).

Figure 1 air outlets on the back panel of the housing

CAUTIONThe test instrument may only be operated when set up at an angle using the combinedcarrying handle and stand (figure 2). Only when set up in this way is unhindered ventilation

guaranteed. The air outlets on the back panel must be kept free at all times.

3.2 Connecting the protective earth conductorBefore any leads are connected to the test instrument, the device must by connected to aprotective earth using the three-core power cable delivered with the test instrument. For thispurpose, the power plug must be inserted in a socket outlet with earthing contact. The earthconnection should not be interrupted by an extension cord without an earth conductor.

WARNINGAny interruption of the earth connection either inside or outside the test instrument cancause the test instrument to become a source of danger. Deliberate interruption is strictly

forbidden!

3.3 Connecting a device to be testedThe device to be tested should only be connected to or disconnected from the test instrumentwhen it is absolutely certain that no test quantities are currently being output.

Please follow the instructions given below when connecting a device to be tested:

Disconnect the device from the plant. Attach the measuring leads to the device to be tested. Use only measuring leads which

conform to the relevant safety regulations.

Use only measuring leads which can be connected securely to the device to be tested viaplug-in contacts or cable lugs.

Remove all superfluous measuring leads.The measuring leads used should be as short as possible. In particular when connecting thecurrent outputs, it is important to check the correct dimensioning of the conductor cross-section.

CAUTIONFor reasons of safety, only cables with safety banana connectors should be used. Themeasuring leads must be fully insulated. During the test, voltages of over 100 V aresometimes available at the output sockets.

3.4 Operating the test instrument3.4.1 Switching on

When commissioning an ARTES 400 II test instrument, the following stepsshould be carried out:

Connect the test instrument to the operating PC via the serial interface located and theUSB interface respectively on the front panel. To do so, use the 9-pole data cable andthe USB data cable respectively provided.

Make sure that the main POWER switch is in the OFF position ("0"). Connect ARTES 400 II to the mains voltage. To do so, use the power cable with earthing

contact provided. First insert it into the inlet socket on the test system and then connectthe cable to the mains socket outlet.

Switch the test system on using the main POWER switch located on the test instrument. The system then "starts up". Various internal initialisation routines are run through first.

After approximately 30 seconds, initialisation is complete and the system is ready foroperation.

The following steps are described in detail in the ARTES User Manual:

Starting the ARTES operating programme Checking the communication interface, selecting a free interface Selecting ONLINE mode.In order to achieve the very highest possible degree of accuracy, it is advisable to observe awarm-up period of approximately 5 minutes before carrying out the first test. The warm-upphase lasts longer if the test instrument has been subjected to extreme temperature

fluctuations (e.g. after being transported in a car).

3.4.2 Operating statusTwo light-emitting diodes are located on the front panel of ARTES 400 II. These LEDs

indicate the communication status.

ARTES 400 II CONNECTIONS AND INTERFACES 10

4 Connections and interfacesAll the connections required for linking the device to be tested to the test instrument are

located on the front panel. Connections are either made via 4mm safety banana sockets.

Figure 3 ARTES 400 II front panel

Individual in- and outputs are combined to form groups which are indicated by the position of

the in- or outputs and the surrounding frames.

You will find detailed information regarding the entire test system in the chapter titled

Technical Data. The technical data included in the present chapter is only intended to providean overview.

CAUTIONIt is not possible to operate the test instrument in an upright position as the leads connectedto the back panel might be damaged and the air outlets would be covered.

4.1 Connections on the front panelThe following inputs, outputs and sockets are located on the front panel:

Connection to power supply, Serial ports, Amplifier outputs, Low-level signal output (LS Out), Direct voltage supply (DC-Aux.) Binary inputs, Ethernet ports, GPS-aerial connection socket, Binary outputs and the Analogue inputsMore detailed information regarding connections is given below.

WARNINGWhen the safety caps are not in place, it is imperative that the safety information andwarnings regarding the amplifier outputs and binary inputs contained in this chapter arefollowed precisely.

4.1.1 Connection to power supplyThe test instrument is supplied with power via the mains connection socket

using the cable for non-heating appliances provided.


11/19


WARNINGThe power cable provided has one earth continuity conductor. If the connection is madecorrectly, the housing of the test instrument is connected with the earth continuity conductor

of the two-pole-and-earth socket-outlet via the earth continuity conductor of the power

cable. Incorrect connection (for example, if non-earthed socket-outlets are used) can causedeath or injury from electric shock!

CAUTIONCheck the mains voltage and frequency before connecting the test instrument. The test

instrument may only be operated within the mains voltage range detailed on the rating plate.Operating the test instrument with an incorrect mains voltage may damage the testinstrument and leads to loss of the guarantee.

4.1.2 Communication portsThe RS-232 serial connection of the test system is linked to the serial connection of the

operating PC via a 1:1 cable (ARTES 400 II: DB-9-connector; PC: DB-9-socket). Do not use anull modem cable with reversed transmitter/receiver lines!

Figure 4 Serial port, 9-pole, SUB-D

The connection can also be established via the USB port. In this case the USB port of

the test system has to be connected via an USB cable to the USB port of the operatingPC.

The USB driver for automatic installation is located at the setup CD inside the folder:

[CD ROM Drive]:\Driver\USB

WARNINGOnly one of the both serial interfaces (either RS 232 OR UBS) should be connected to thetest system. To conncect both would lead to communications problems.

4.1.3 Amplifier outputsARTES 400 II has four voltage and six current amplifiers whose output signals can be set

independently from one another as regards amplitude, frequency and phase angle. Thecurrent and voltage amplifiers are electronically overload and short-circuit protected.

The test quantities are calculated from the parameters entered via the software and aresupplied to the device under test by means of digital-analog converters and amplifiers.

Because the test quantities are generated synthetically, they are unaffected by disturbancesin the incoming supply.

The test quantities generated by ARTES 400 II are supplied to the amplifier outputs and canbe accessed there. The amplifier outputs are arranged in groups:

Voltage Output (voltage outputs) Current Output (current outputs)


12/19


4.1.4 Voltage outputsThe three test voltages generated by the instrument are available via

the sockets of the Voltage Output group. All output voltages refer to

the common point of reference N (blue connection socket).The output range of the voltage amplifiers is defined as detailed below:

3-phase 3 x 0 to 300 V, 3 x 75 VA 1-phase 1 x 0 to 600 V, 1 x 150 VA

CAUTIONIt is important to note that an external voltage must neither be applied to the voltage

outputs nor should the voltage outputs be wired parallel otherwise the amplifying equipmentwould be destroyed.

4.1.5 Current outputsThe currents generated by the test system are also available via the

sockets of the Current Output group. The six current channels are freelyconfigurable as regards phase, amplitude and frequency. The current

outputs are divided into two groups (Current Output I1 to I3 and CurrentOutput I4 to I6). All output currents refer to the common point ofreference N. The blue sockets for the reference point of the first andsecond Current Output group are directly connected inside theinstrument!

The current amplifiers of the ARTES 400 II test instrument provide a maximum test current

of 12.5 A per channel. If higher test currents are required, the amplifier outputs can beoperated in parallel. If you require test currents of 3 x 25 A for three-phase tests, then the

following pairs of outputs should each be wired in parallel: I1 and I4, I2 and I5 and I3 andI6.

You can connect suitable shorting jumpers directly to the sockets of the front panel to wirethe outputs in parallel. To keep power losses resulting from the connection between the testsystem and the device under test to a minimum, it is best to take a separate connecting linefrom each output to the device under test and then connect them in parallel directly at the

terminal of the device under test.

The test quantities are only output correctly during parallel operation if the correct settingshave been made in the ARTES software (see the ARTES User Manual for detailedinformation).

The following amplitude and power data is valid for three-phase systems with symmetricalconditions:

6-phase 6 x 0 to 12.5 A, 6 x 40 VA 3-phase 3 x 0 to 25 A, 3 x 85 VA4.1.6 Low-level signal outputs (LS Out)

The low-level signals required for controlling external amplifiers or for testingprotection relays with low-level signal inputs are available via the LS Out socket

of the ARTES 400 II. The signals supplied by this socket lie within the range of 0to 10 Vpk.

The table below shows the pin assignment of the LS Out socket.

4.1.7 Direct voltage output (DC Aux.)An optional direct voltage output for supplying digital protection relays is located on

the front panel of the ARTES 400 II. This output is labelled DC Aux. (auxiliarypower supply). The direct voltage available via this output can be controlled by theARTES software within a range of 12 to 260 V. 50 W output power is available.

4.1.8 Ethernet portsThe test system can be optionally equipped with two Ethernetports, which are labelled ETH1/Sync. and ETH2. These ports are

used to carry out protective function tests in accordance with IEC61850. They can also be used for communication with additionalexternal equipment.

4.1.9 GPS aerial connection socketThe test system can be optionally equipped with an internal GPS module. Using the

GPS aerial connection socket, the GPS aerial can be connected to the ARTES 400 II.

This connection socket is labelled GPS.

4.1.10 Binary outputsThe Binary Output group of the ARTES 400 II provides two binary outputs inthe form of switched relay contacts. The timing sequences of the individual

outputs are freely configurable. The contacts of the output relays arepotential-free and galvanically isolated from one another. The switchingcapacity of the relays is:

AC 0 to 250 V, 8 A, resistive load

DC 0 to 300 V, Imax = 8 A, 50 W resistive load

4.1.11 Binary inputsThe test system has eight binary inputs which are protected against polarity reversal and arelocated within the Binary Input frame.

These inputs are arranged in two groups of four channels. The connecting lines between thepoints of reference of the individual binary inputs signify the individual groups.


14/19


CAUTIONWhen connecting a device to be tested, it is important to note that the points of reference ofthe binary inputs of a group (1 to 4 and 5 to 8) are directly connected to one another inside

the test instrument.

The inputs of both groups can be used as potential-free or potential-carrying inputs. Use theoperating software to switch between the two options (please consult the ARTES User Manualfor details).

For reasons of safety, if you have configured the binary inputs as potential-carrying in thesoftware, the voltage concerned is only available at the sockets during tests.

4.1.12 Analog inputsEight input sockets arranged in two groups are located on the font panel for themeasurement of analog quantities. The inputs of theAnalog Voltage Input group are used

for voltage measurement, while the inputs of the Analog Current Input group are used forcurrent measurement. The inputs are equipped for the following measurement ranges:

U 0 to 10 V

I 0 to 20 mA I 2 V ~

ARTES 400 II MAINTENANCE AND SERVICE 15

5 Maintenance and serviceARTES 400 II contains no parts which can be serviced by the user.

A dry cloth should be used to clean the test system.

CAUTION

Never use solvents or water to clean your test instrument.

5.1 TransportTake care when transporting the test instrument! If possible, always use the bag provided.Never drop the test instrument or allow it be knocked over. When transporting the testinstrument, make sure it is always in a stable position and cannot fall down, slip or tip over.

CAUTIONNote that knocks and vibration may damage the test system.

5.2 CalibrationChanges in the amplification and/or offset of the current and voltage amplifiers may takeplace over time as test system components age.

As with all precision measuring instruments, regular calibration is necessary in order to en-sure that the ARTES 400 II is functioning correctly. We recommend that the test system becalibrated on a yearly basis.

ARTES 400 II has been specially designed to allow calibration by the user. This means thatno operation time need be lost through sending the test system to our factory or to one ofour branches or agents.

Calibration of the test instrument is controlled by the software. All calibration parameters arecalculated automatically and are saved permanently and safely in the test system in a flashROM. There is no need to open the device and make adjustments using potentiometers etc.

as all signals are generated synthetically.

Please note that the accuracy of the calibration depends on the accuracy of the measuringinstruments used for the calibration. If the necessary measuring instruments are not

available, ARTES 400 II should be sent to us for calibration.

Measuring instruments for both direct and alternating voltage and direct and alternatingcurrent are required for the purposes of calibration. These measuring instruments are used

to measure the various output signals (set values) of the amplifiers. The measured quantitiesare automatically set and displayed by the programme in accordance with the systemconfiguration. The date of the most recent calibration is also saved in the test system itself.

More detailed information regarding calibration of the test system can be found in the ARTESUser Manual.
