protection function useequivalenciesThis section highlights the mostimportant points.

Explanation:For Sepam 2000, if a fault ispresent for a time period longerthan the protection time delay, theprotection contact changesposition, so that when the contact isused in the control logic, thedesired effect takes place instantly.

Protection function processingin control logic is differentin Sepam 2000.In Sepam 15, it was possible for aprotection function to be activatedby the occurrence of an externalevent.This no longer exists inSepam 2000, in whichthe instantaneous and time-delayedprotection contacts are alwaysavailable.

Sepam 15 Sepam 2000X15 (1)

The user must declare which available The user simply uses the protectionprotection functions he wishes to use in the function contacts (2) in the control logic.control logic and then use the correspondingcontacts.

In replacing Sepam 15 bySepam 2000, two main parts mustbe distinguished: physical interface part, logical interface part (protocol),i.e. programs, addresses and dataformats with the special case oftime tagging.

presentation

Sepam 15 communicationCommunication takes place via anasynchronous serial link in a 4-wire(two twisted, shielded pairs) 20 mAcurrent loop .If the communication port of theupper level is of the standardizedRS232 serial link type, an interfaceconverter is necessary to transformthe RS232 link into a current loop(Fig.1).

Sepam 2000 communicationtakes place via an asynchronousseril link, in voltage differentialmode of the standardized RS4852-wire (twisted, shielded pair) type.If the communication port of theupper level is of the standardizedRS232 serial link type, an RS232/RS485 interface converter isnecessary (Fig. 2).

Extension of a Sepam 15networkTo extend the Sepam 15 networkwith Sepam 2000, a 20mA currentloop / RS485 converter is added(Fig. 3).In order to simplify processing atthe upper level and take advantageof Sepam 2000 's speed, it isrecommended to have a secondserial port, if possible, as indicatedin Fig. 4.

Replacement of Sepam 15To switch from a Sepam 15 networkto a Sepam 2000 network, twocases are possible: case 1:The serial port of the upper level isan RS232 link.Simply replace the RS232 / currentloop converter by an RS232 /RS485 converter ( Fig.2). case 2:The serial port of the upper level isa current loop link.Simply install a current loop /RS485 converter. there are two types of current looplinks: 0mA deactivated or 20 mAdeactivated (so there are often twotypes of current loop converters).The connection cable may bereused since the RS485 networkuse a "twisted, shielded pair"cables.It is recommended to use CCA 609connection boxes and to observethe cabling precautions describedon the next page.

Cabling precautionsThese precautions are aimed atensuring cable shielding continuityand correct grounding.The CCA602 branching cablesprovide shielding continuitybetween Sepam 2000 and theconnection boxes; Make sure that the twoconnectors at the ends of the cableare plugged in correctly and lockedby the two screws speciallyprovided.Shielding should be continuousthroughout the RS485 network.Each box includes two cableclamps.They ensure cable shieldingcontinuity and grounding via theterminal specially provided. Make sure that the clamps aretightened onto the metallicshielding braid and not onto theinsulation. Make sure that each connectionbox is grounded by the 2.5 mm2

"green-yellow" wire or a shortconnection braid (less than 10 cmlong).For electrical distribution systems inwhich the earthing systems arenot equipotential or separated, thestipulations made by the standardsin effect should be applied.A "low voltage" type cable trayshould be used for the RS485communication network cable.For further information andrecommendations, please refer tothe Telemecanique TSX DG GND Fdocument entitled, "groundingcabling guide".

logical interfaceJ-BUS is the same for Sepam 15and Sepam 2000 ;the J-BUS function codes are thesame.However, the accessible data is notthe same in Sepam 2000 and thedata tables are structureddifferently (content, addressing,data format).The program of the upper levelmust take account of thesedifferences.

(*) With the communication option, Sepam 2000 offers the user the possiblity of reading the protection settingvalues (limits, time delays) set in Status.(1) The Sepam 2000 control logic internal relay contacts are not directly accessible via J-Bus communication.They are reproduced on the relay contacts called KTS.(2) Please refer to the manual entitled "J-Bus communication", n° 3140751A-C.(3) Available as of 02/95 versions of Sepam 2000.

time tagging The time tagging principles used inSepam 15 and Sepam 2000 arequite different and may not be usedat the same time in the sameSepam line or loop. It is imperative to use thescheme in Fig. 4 (see "physicalinterface") and to create 2 timetagging management programs.Sepam 15 uses a chronologybased on counting the timebetween events whereas Sepam2000 uses absolute time tagging ofevents.Initialization and management ofthe time bases are different.The event stack and tableaddresses and formats are notmanaged in the same way either.

The program of the upper levelmust take account of thesedifferences.Programmers should refer to theSepam 2000 J-BUS communicationmanual, n° 3140751, regarding thedefinition of time taggable bits,initialization, management of thetime base, management of themethod of unstacking time-taggedevents and treatment of anomalies.

Accuracy CS20 non-magnetic toroidThe degree of accuracy remainsthe same as that announced forSepam, i.e. composite error of±0.5% .

CS100 non-magnetic toroidThe degree of phase accuracy isdowngraded by an additional errorof 0° to +1°, which adds about 0%to +1.5% to the composite error of±0.5%.This error is due to scattering of theinternal resistance of the CS100toroids.

zero sequence toroids /CTs

This chapter specifies thecompatibility between Sepam15zero sequence toroids andSepam 2000 core balance andinterposing ring CTs. Sepam 15 toroids MN (diameter 120, white), SN (diameter 200, white), TF (diameter 30, green), PF (diameter 50, green), MF (diameter 100, green), SF (diameter 200, green), GF (diameter 300, green), PO (diameter 46, split), GO (diameter 110, split). Sepam 2000 CTs CSH 30 (diameter 30), CSH 120 (diameter 120), CSH 200 (diameter 200).

AccuracyThe Sepam 15 toroids have thesame winding ratio as the CSH CTsdesigned for Sepam 2000. Theyare therefore compatible withSepam 2000.The ± 5% degree of measurementaccuracy is the same.The phase accuracy of the previousgeneration of toroids is not known. Do not use Sepam 15 toroids fordirectional earth protections...

Toroid/CT polaritySepam 15 toroid polarity was notindicated on the devices (P1, P2).When zero sequence toroid polarityis important (directional protection),the connection should be checkedusing the test described below: make sure to observe thedirection of power flow.To detect the direction in which thetoroid is mounted, perform thefollowing test: when d.c. current is cut off,the ammeter needle should movein the negative direction beforereturning to 0, when d.c. current is applied,the ammeter needle should movein the positive direction beforereturning to 0.

Notes :There are no saturation problemsfor the 2A rating, whatever thetoroid, up to a wiring resistanceof 10Ω.With the 30A rating, up to a wiringresistance of 1Ω, there are nosaturation problems for any of thetoroids except for CSH30 and TF.The MN toroid (diameter 120 white)saturates above a wiring resistanceof 1Ω for the 30A rating.The CSH120, MF and PF toroids,however, only saturate as of 4Ω.Do not use CSH30 and TF toroidswith a wiring resistance greaterthan 5Ω for the 30A rating.

Toroid / CT saturationThe constraints given inSepam 2000 technical manualsmust be observed when CSH CTsare used.These constraints define themaximum operating current Immin accordance with the wiringresistance (Rf).The following graph includes theSepam 15 toroids.

23

CablingThe cabling constraints imposed bySepam 2000 must be observed: use of sheathed, shielded cable, when the cable shielding isgrounded via Sepam 2000,no other grounding should be used.Please refer to the Sepam 2000instruction manuals.

1A or 5A core balance CTWith Sepam 2000, residual currentmay be measured by a standard1A or 5A core balance CT.The CSH30 interposing ring CT isused as an interface between theCT and Sepam.For reasons of accuracy, no otherCT (old or new generation) shouldbe used in place of the CSH30.
