Which
of the following features is NOT desirable while protecting a transmission
line?
Simultaneous
reclosure
Independent phase relaying, etc.
Multiple
pole switching
Discrimination between external and internal faults
Multiple
pole switching
Desirable
feature of protecting a transmission line :
1.High reliability
2.Simultaneous reclosure
3.High relay speed
4.Discrimination between external and
internal faults
5.Independent phase relaying.
Multiple
pole switching in relay is used to improve transient stability of the
transmission line.
Hence,
the correct option is (C).
