We have 11kV/110V three phase indoor potential transformer in 66/11kV Sub-station, where the failure of PT is frequently happening and the rating of the PT is 0.2 class accuracy, with primary star and seconday (two cores) star connected. Some experts has suggested to not to connect the PT Primary neutral to the ground because when transformer neutal NCT connection is loose; the faulty current will flow through the PT primary neutral, resulting into failure of PT. My question is: Is it necessary to remove the primary neutral connection of the PT from ground? if not, what would be the reason for failure of PT. Please guide me.

11KW Delta motor is taking about 44Amps in star and goes upto 70Amps in delta and trips OFF. The rated current is 26Amps. Application is for the blower. The motor takes ( no load without coupling impller ) only 2.5A and 5Amps in star & delta starter test.Need to know why its taking high current.
