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 / 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.

I have made a 3 phase thyristor full bridge rectifier. But at the moment it is working only for the half bridge operation. Both the half bridges are on operation separately but when i put it into full bridge operation the oscilloscope output is zero. I rechecked that the pulses are correct for each thyristor. what could be the possible reason for this?
