|there is a power transformer 66/11kV in delta-delta
connection has 5 feeder coming out from the secondary side.
One of the feeder in it normally loaded (loaded than other
feeder)and this feeder usually trips with double OCR causing
the bank transformer to trip. Now if the load of this feeder
is put on other transformer then that no problems occurs on
that transformer or the load. However normally all the
test(IR, PI, short ckt, open ckt,grounding test and other )
has been conducted for this but evertything transformer.....
I am not geting what is the actual problem...
