For veryfication of oil purity every year to be checked the
BDV(breakdown voltage),we have take out the transformer
oil in the transformer and collect in the high voltage kit
inthe kit two stem will be there within the 2mm gap and
then apply the high voltage 50kv for 1 minute and it
shiould be withstand upto the mentioned time.Otherwise oil
to be filtered.

can we use NPT glands in LT panel

WE know that for Inductor X=2pifL,In DC f=0,then X=0 so,V=IX=0;But In the DC excitation of rotor of AC generator,DC motor field coil which coils are inductor so why does not applying DC voltage short the rotor coil of AC generator and field coil of motor?If it would then DC source might be damaged but it is not happened. Why does the strand conductor of Electrical power transmission line make twist?
