What will be the minimum megger value of 1700 KVA Transformer?
a) Do megger value varies according to climate conditions
and area .
b) If megger value is 100 mega ohm is it good for new
transfomer.
Explain?
Answer Posted / 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.
