How the Transformer oil testing is done & Why oil dielectric
goes LOW & what is solution for that ??

Answer Posted / ravikumar.g

The transformer Oil testing to be done in filtration unit
by checking the Oil Testing Kit in KV

20 KV low

when the voltage are not balancing properly and the taps
are changing regurly the oil becomes carbonsied this
carbonsied oil is acts as conductor.

So these problem so we change the Oil.

The salution for this changing the oil the transformer has
to be oilfilteration in once in a year.
