If we take the LT panel incoming of the breaker is 1600A
and the transformer rating is 2000KVA.
We have to select the cable for that t/f to incoming
breaker in LT panel
400Sqmm AL cable carry 315A (POLYCAB) then we go for 6Runs

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.
