DOES AN EARTH FAULT CURRENT ON THE DELTA SIDE OF A 6.6/33KV STEP UP STAR-DELTA CONNECTED TRANSFORM..

Answer / k.prakashchandra

There can not be earth fault on delta side as there is no
neutral for earthing and the neutral of the primary gets
isolated .It is customary to have delta -star step up
transformer instead of star-delta.
