what do you mean by earth fault in transformer?
Answer Posted / nilkanth tailor
EARTH FAULT REQUIRE C.T.(CURRENT TRANSFORMER)..TO SENSES
IMBALANCE IN 3 PHASE..GENERALLY 3PHASE SYSTEM IS IN BALANCE
CKT...IF SINGLE OR MULTI PHASE WAS EARTHED..AND AT THAT
TIME IMBALANCE PRODUCED..CT WILL BE DETECT FAULT CURRENT
AND CIRCUIT BREAKER WILL BE OPEN...THATS CALLED EARTH FAULT
PROTECTION OF X'MER...

Assuming that a dedicated neutral earthing transformer is provided for each GT generator, when the two generators are running in parallel, has consideration been given that the earth fault current from one generator stator winding be split between the two neutral earthing transformers? If so, what adverse impact will this have on the operation of the 59N and 27TN devices?
