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.

We know that primary transmission is done to reduce current so that i^2*r loss could be minimised but according to ohm's law v is directly proportional to i,which indirectly means higher potential difference means larger current?so how the current is minimised in high power transmission line??
