tests i can do to know the performence of transformer and
also please tell me about the BDV test and Insulation
resistance test in oil cooled transformers

Answer Posted / pinaki chatterjee

according to all routine test as per IS-2026 PART 1 and magnetic balance, also current balance test should be require if necessary temperature rise test can be made.

if the voltage level is 11 kv so IMPULSE TEST AS PER clause 12 can be made for better acivement.

partial discharge should always check
