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.

In the solution of load flow eqation, Newton raphson method is superior to the gauss siedal method because (a)the time taken to perform one iteration in the NR method is less when compared to GS method (b)the number of iterations required in the NR method is more compared to that in the GS method (c)the number of iterations required is dependant on the size of the system in the NR method (d)convergence characteristics of the NR mehod are not affected by the selection of the slack bus
