Hello,
I have an issue with my transformer charging.Transformer ratings are 110 MVA,132/11 kV Three phase.This transformer has to be commissioned in a short period .But the problem is there is no 132 kV supply line from the switchyard which is in under construction.My question is...
I am having an issue with megger values between frame and transformer tank.the values are coming zero.the rating of the transformer is 7.5 MVA,132/11 kv.
The transformer is in nitrogen filled condition.
Please tell me the reasons and the after effects due to this.
