I have 11KV/415V power distribution transformer. I have found unbalance current in LT (415V) side. Also observed that unbalance voltage (3V) at LV side due to HV side unbalance voltage. What should I check for this? Also, the same LV side load can run in balance on captive power.

If I want to lift the water at a height 50m from ground level through two inch(diameter) metal pipe then what is the capacity of motor pump is required? is it possible in single phase supply or not?
During the main stator winding insulation testing (phase to ground)of 11kv alternator (Lerysomer) i found 0 and resistance with multimeter and found 20 killo ohm while the power cables are connected both end (Generator & VCB). In VCB PT (Potential transformer) are connected. Please any body explain that method of insulation is correct or not? also describe of PT connections
