how to calculate the neautral earthing conductor size for a
500kva dg set.
Answer Posted / krl raju
If alternator voltage is considered 415 V, then rated
current of the Alternator is
=500*1000/(1.732*415)=695.6Amps.
Hence we need to select the neutral conductor to withstand
the half of the full load current i.e 350Amps
