What will happen if a new branded 132KV transformer is charged at the IR value of 150Megaohm between HT winding and Earth remaining IR values being found infinity?

Answer 1

Sir I am Imran khan in Nepal my problem is 6000KVA Step down Transformer is not charging. Transformer Pri- 33000V /105A Sec- 6900V / 502A

transformer all test (open & short circuit ) good . but problem is HT(IR)= value this time IR value 50M ohm

Before 3days HT(IR) = value is 7000M ohm suddenly start Transformer result is Transformer not charging & HT(IR) value is down 50M ohm.
