difference between shunt coil and tripping coil
Answer Posted / ravishankar.ck
There are to methods of tripping the MCCN, ACb, VCB or SF6 one is Shunt trip operated by DC voltage or AC Another is Series trip works or current
with small voltage developed by CT which does not require any auxiliary supply coil and trip coil As it the shunt trip must be tripped with auxiliary supply this can also be used for tripping during the fault using protective relays. The relay will sense the voltage or current excesses beyond preset value through CT/PT and gives a xommand to shut trip coil and trips breaker LT, HT or EHT
