As time graded system gives long time delay in fault clearance at the generating station, also. A relay is used to. distance relay is superior to overcurrent protection for the protection of transmission lines. Relays For Transmission Line Protection Are Mcq option 1 : For the protection of a very long extra high voltage line, the protective relay used is. reactance relay is suitable for the protection of a short transmission line because its operation is independent of arc resistance.

In impedance relay, current element. Isolators used in transmission lines are capable of breaking. Relay is preferred for phase fault on short transmission line. the physical construction of the transmission line is also a factor in protection system application. In long transmission lines power swings are more frequent. Only up to 110 kv. distance protection of transmission lines. Relays For Transmission Line Protection Are Mcq.
