Good evening brother, in case reverse zone fault , due to CT error , if sub Y assume the fault as zone 1, it's already tripping substation Y.. substation X is prevented by zone 2 pick up verification..how to safe substation Y from tripping Incase of CT error
if the fault current is high even CT malu operated but still voltage drop occurs and it will trip by voltage protection too. but fault isolation time will be high

Anna,Auto reclosure&Pole discrepancy timing and their coordination pathi sollunga.
yes bro
Super sir
thank you.
Bro directional over current and earth fault relay videos podunga
yes bro soon
What is direct trip send, receive??? How this scheme working???
i will make on video on Direct trip
Mutual compensation solunga bro
okay bro
What is the difference between PUTT and POTT where we will use this application bro
