Effect on Primary

11/06/2010 10:38 AM

There is a Transformer of rating 13./6.6 KV, 10MVA, /Υ. If a ground fault occurs between one secondary phase, say r phase to ground then will it be sensed in primary() also either by Over load or instantaneous over load? Pls make me understand with necessary calculations.

Homework question?

It would appear so as you only suggest a fault on R phase.

You have to work it out yourself otherwise you gain nothing.
A quick scenario for you, your tutor asks how did you arrive at the answer, how are you going to reply?
