diffrential. All the relay'S contact will connet parelly to master trip relay. if any of the protection rely sence the fault... it will energise the master trip rely and the master trip relay will trip the breaker.it got one more name like lock out relay. Is This Answer Correct ?

Answer (/Viewpost/384347/Master-Trip-Relay-86-Main-Tripping-Protection-Scheme-Actually-Breaker-PolesActs.Html) / Linu Mohan master Trip relay 86 is the main tripping relay in the relay protection scheme.It is actually tripping the breaker poles.It acts because of the stimuli from any of the protection relays.It's tripping coils are related with the actuators from different relays.For example Directional overcurrent relays and earth fault relays Is This Answer Correct ?

Answer (/Viewpost/470753/Function-Master-Trip-Relay-86-Main-Pick-Up-Coil-Circuit-Breaker-If-ProtectionRe.Html) / Vinod FUNCTION- Master trip relay 86 main function is to pick up the trip coil of the circuit breaker, relay 86 pick up if any of the protection relay of the respective feeder or equipment operate. 86 relay is a manual reset relay (its avoid multiple charging of the faulty system with unknown operators) USAGE: The relay pick up through the protection relay contact(static or numerical) have less current rating, it can not carry the trip coil current of the circuit breaker Is This Answer Correct ?

Answer (/Viewpost/472302/Transmission-Disttribution-System-High-Voltage-Line-Many-Protection-RelaysUsed-.Html) / Satya Rout (Oeg Rr) In a transmission & disttribution system a high voltage line there are so many protection relays are used like-distence relay, overcurrent & overvoltage rly, earth fault rly, diffrential rly . All the relay'S are connet paralley to master trip relay. if any of the protection rely sence the fault... it will send a voltage signal ,then energise the master trip rely coil and the master trip relay will trip the breaker.

Grounding. Dear all at one of my site we checked the amps at the earthing cable to the alternator it was found 125 to 130 A. at the neutal cable in same machine found 146A. in the same plant checked the earthing current on other alternator it was 52A, and neutral 116 A. we are facing problems with our controller and the card was damaged once. can that neutral/GND current be a reason? as there is common grounding for the Alternator,Brkr panel,Transformer?
