TRF oil is tested in a glass pot where high voltage,KV is
applied between two electrodes and sparking at electrode to
be observed. For good oil , it comes about 40~60KV/mm .If
it comes lower then filteration is required. Those TRF
having tap changing is frequently required it is
recommended to do filteration in once in year.Also its
value goes low because of moisture ingress in oil .
