Dear Sir,
we met a disaster with our 62.5 kva genset, after rewinding
we informed by our contract engg that due to return current
coming in neutral & impropper earthing this happend.
But after all set up & load balance we checked & found
again we have about 20 to 32 amp return current on neutral.
we have 12 airconditioner + 12 mini fridge on single phase
line.
Pl suggest any idea to solved this problem

i have a 4 Mva transformer 34.5 kv / 480-277 v and i used 2 parallel 3200 amp bus duct for the secondary feeder using 3 ply of bus bar ( 3/8" x 5" ) as a common where the flexible link terminated and 6300 amps breaker for the main, the lower bus duct reaches 70 degrees and the upper bus duct reaches 55 degrees when i used thermal scanner. why the temperature is not balance when the load reaches 3600 amps.
