Answer Posted / k.prakashchandra
At least, two current coil connections are reversed.There
are usually 8 terminals in a 3 phase EM. From left, termial
no. 1,3,5 are for main side (incoming) for the 3 phases and
2,4 and 6 are for their load side .7an8 are for neutral and
are shorted inside the meter.This reverse rotation usually
takes place when CTs are used and directions of currents
are reversed.
