Before use : storage conditions

Sepam must be stored in good condition to avoid any life time reduction :

– In it’s factory package

– In dry and clean place

– Temperature does not have to exceed -25°C/-13°F and +70°C/+158°F

– Exposure to continuous damp heat : 93%RH +40°C +104°F does not have to exceed 56 days

– If storage must be longer than a year, Sepam should be energized for one or two days every year

INSTALLATION RULES

Installation rules


Generic rules : earthing

Refer to document :

“MV protection relay installation assistance guide” ref 51312779F0 A2

Guarantee an equipotent bonding network

Connect every equipment to earth



Generic rules : disturbing and sensitive cables

Disturbing cables are :– Power circuit in general, Welding machine power supply in particular– PEN and PE conductors– Control circuit including inductive loads : relays, contactors,…

sensitive cables are :– Communication circuits– Analogue measurement circuits : unbalance CT input, Temp sensors

Avoid the parallel running of disturbing and sensitive cables

Or assure separation distance between disturbing and sensitive cables

Disturbing and sensitive cables must cross at right angle



Generic rules : ground loop

Minimize ground loop areas : cables must be as close as possible from earthed metallic part

A ground loop results from the area between an active conductor and the ground.



Generic rules : I/O

Outgoing and incoming I/O cables must be together

Shielded cables are grounded at both ends

(only if both sides are equipotent by an other way !!!) Free conductors in cables must be earthed at both ends Unused input must be shorted to earth



Cubicle prerequisite

Switchgear must be connected to building earth

Every metallic parts of cubicle, including doors, must be connected together and to earth by wide conductor on non paint parts


CTs and VTs secondary common point should be connected to main earth terminal (rectangular copper bare) of cubicle in MV compartment

LV compartment should also have a main earth terminal directly connected to the LV compartment one and on witch each equipment should be connected


Power supply requirements

Nominal range : 24 / 250 VDC or 110 / 250 VAC (47.5 / 63 Hz) Absolute range ( -20 / +10% ) : 19.2 / 275 VDC or 88 / 275 VAC

Series 80 accept only DC voltage supply Nominal range : 24 / 250 VDC Absolute range ( -20 / +10% ) : 19.2 / 275 VDC

Focus on DC supply :– Rectified only should not be used because it will reduce lifetime – Acceptable ripple content on DC voltage : 12%

Wiring requirements and accessories

Power supply and I/O : 2 different types of connector :

CCA620 : screw type CCA622 : ring / spade lugs Ø4mm

Telemecanique ZD5 series

For both type, wires are single 0.2 to 2.5mm² / AWG 24 to 12or maximum 2 wires 0.2 to 1 mm² / AWG 24 to 16

1mm² will be preferred for I/0 when used I/O number is high and if this size is correct for the application

Current sensor inputs

CCA630/CCA634 connector

The CCA630 connector is used to connect 3 phase current transformers to Sepam

The CCA634 adds an input for a residual current transformer : do not connect a core balance ct

With CCA634 Io input on A or E connector must not be used.

Both contain interposing ring CTs with through primaries and be disconnected with the power on since disconnection does not open the CT secondary circuit.


CT 1 or 5A


Phase current inputs : 3 CTs / 2 CTs

CCA630/634 connector– connection of 2 or 3 CTs

– complete parameter setting using SFT2841 software



Phase current inputs : CTs wiring


Power consumption in cables :

CT must feed all connected equipments : SEPAM, ammeter,…, and cables !!

Pwire = I² x ρ x L / S ρ = 1,728 10-8 at 20C° L = wire length, go and back, in meter

e.g. : CT secondary : 5A S = 1.5mm² L=30m P = 8.6 VA

CT secondary : 5A S = 4mm² L=30m P = 2.2 VA


Phase current inputs : LPCTs

CCA670 or CCA671 connector– connection of 3 LPCTs

(Low Power Current Transducers)– parameter setting using SFT2841

software, completed by hardware setting of microswitches


Residual current inputs : CSH 30/120/200


CSH120 or CSH200 core balance CT– ratio of 1/470

CT + CSH30– connection of CT with secondary

– 1A: 2 turns– 5A: 4 turns

– Or direct on CCA634


Residual current inputs : recommendations


Cabling recommendations The CSH120 or CSH200 core-balance CT is connected directly to the Sepam

connector. Recommended cables:

A twisted two-wire connection is recommended.

Shielded cable may also be used

The maximum resistance of the Sepam connection wiring should not be more than 4 Ω.

CSH 30 must be placed in a low magnetic activity area in LV compartment : e.g. away from auxiliary transformer


Residual current inputs : recommendations



Residual current inputs : core adaptation


ACE990 interface– use of a core balance CT with a ratio of 1/50 to 1/1500– Only one core by ACE990

Connecting Sepam and additional modules to earth is compulsory.

All output relays are not identical :– Some are control type with 8A continuous current

• For Sepam 20/40 : O1 / 02 / 011• For Sepam 80 :O1 -> 04 et O101 / O201 / O301

The availability of some protection functions depend on VTs wiring
