7. 220/132/110/66kV transmission line circuit-1 P.T. fuse fail (wherever required). 8. 220/132/110/66kV transmission line circuit-2 P.T. fuse fail (wherever required). * There is no separate telesignal for PT fuse fail indication. The annunciation for PT fuse fail indication shall be done in case of any inconsistency between the status of feeder circuit breaker/paralleling interruptor and the catenary indications. (Feeder circuit breaker/paralleling interruptor when under power block is to be treated as ‗open‘ for this purpose.) (b) For each Scott-connected/single phase Traction Power Transformer, Auto transformer and associated switchgear (i) From transformer-1 *9. TR-1 Alarm. **10. TR-1 Fault ***11. TR-1 Trip circuit 110V dc fail <strong>12</strong>. TR-1 220/132/110/60 LV circuit breaker ―Locked –out‖ due to low gas/air pressure. 13 TR-1 25kv CD-1 ―Locked out‖ due to low gas/air pressure 14-19 TR-1 tap 1 to 6 position 20 TR-1 Blower fans working 21 TR-1 25kV CB-2 ―Locked-out‖ due to low gas/air pressure (In case of Scott-connected transformer only). * TR-1 Alarm: This has to come whenever any alarm viz. Buchholz Alarm, pressure relief device alarm, oil/winding temperature my high alarm and low oil level alarm occurs. ** TR-1 fault: This has to come whenever the inter-trip relay (which trips both HV and LV breakers of the transformer) operates. *** TR-1 trip-circuit fail: Whenever the 110V dc supply to the control circuits fails or any of the trip circuits of 220/132/110/66kV or 25kV transformer circuit breakers fails. Necessary auxiliary contacts of various relays/indicators suitably wired up and terminated on the control and relay board at traction sub-station shall be provided by the Railways. Suitable relays or circuits required in the RTU at TSS for the telesignal shall be provided by the successful tenderer. (ii) From Transformer-2 22 to 34-as for TR-1 (iii) From Transformer-2(as required) 35 to 47-as for TR-1 (iv) From Auto Transformer-1 *48. AT-1 Alarm **49. AT-1 Fault * AT-1 alarm: This has to come whenever any alarm viz. Suchholz alarm, pressure relief device alarm, oil/winding temperature high alarm and low oil level alarm occurs. ** AT-1 fault: This has to come whenever any fault in the transformer is - 8 -
indicated by operation of Buchholz relay, pressure, relief device, winding temperature indicator and oil temperature indicator. Necessary auxiliary contacts of various relays/indicators suitably wired up and terminated on the control and relay board/terminal board shall be provided by the Railways. Suitable relays or circuits required in the RTU for the telesignal shall be provided by the successful tenderer. 5 From AT-4 (v) From AT-2 (vi) From AT-3 50-51-as for AT-1 52-53-as for AT-1 54-55-as for AT-1 (c) Common telesignals for TR-1 to TR-3 and AT1 to AT4 56. 110V dc supply for alarm circuits fail. (d) For each feeder circuit breaker (i) For feeder-1 (ii) For feeder CB-2 57. Feeder CB-1 DPR operated. 58. Feeder CB-1 instantaneous OCR operated. 59. Feeder CB-1 Delta-I relay operated. 60. Feeder CB-1 ―Locked out‖ due to low gas/air pressure 61. Auto-recloser for CB-1 ―Locked-out‖. 62 to 66-as for feeder CB-1 (iii) For feeder CB-3 67 to 71-as for feeder CB-1 (iv) For feeder CB-4 72 to 76-as for feeder CB-1 (c) For shunt capacitor bank control (as required) (i) Bank-1 (ii) Bank-2 77. CB ―Lockedout‖ due to low gas/air pressure. 78. PT fuse fail 79. Shunt capacitor bank fail 80 to 82-as for bank-1 * The shunt capacitor bank may be provided with a potential free 11/0 contact - 9 -
