If total loss in cable is 3 Kw hence it must be devided n
al 3 phases and hence 1 KW loss in one phase, now you can
use frmula P=I*I*R.It comes around 2.083 Milli ohm.

Answer / k.prakashchandra

Yes

Answer / shyamkr

i think the current I will be the r.m.s value of current not
he average value and P will be the power loss in the cable.
so the formula P =I(r.m.s)2 * R.then this formula will give
the resistance in the ac circuit.

What is principal to reduce earth leakage current with isolation transformer? When isolation transformer is installed in input stage of system, earth leakage current is reduced. the reason is why the leakage current of 2nd stage of isolation transformer does not affect the 1st stage's leakage current. I would like to know the reason. As you know, earth leakage current is a kind of AC. So, How to reduce earth leakage current in case that isolation transformer is used?
