What will be the minimum megger value of 1700 KVA Transformer? a) Do megger value varies accordin..

Answer / pillay

minimum meggar value of any electrical installation is best
determined by the operating voltage rather than KVA.higher
the operating voltage higher the meggar value should be.
Climatic conditions can influence meggar value, but any
climate or location the meggar value should be above the
safe accecpted value.

Answer / shariff

There is no minimum or max. value for any transformer
Insulation resistance values( not megger value),the main
factor here is the polarization index value .ie, the IR
value should decay with the time of the time of applied VG.
and the ratio of PI should be morethan 1,and the climatic
conditions will decay the IR values.
