1)we r having one problem .one dry type
transformer(6.6KV/433V)is taking high magnetizing current on
delta connected HV side of "U" phase when compared to other
two phases.could any body tell the reason why it is happening?
2)why CT secondary side protection core has got higher
winding resistance when compared to that of metering core of
same CT?
