Answer / pratap choudary

It affects metering only... Power factor will be indicated in leading...

Answer / k.prakashchandra

All the meters and relays with both voltage and current
inputs will function in the opposite directions

Answer / karan

if CT use as a protection then relay Operate for reason
revers current and another case CT use as metering then
meter slowly moving

Answer / munish

if changes CT polarity than current flow in reverse
direction & it trip the circuit without any fault.

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...
