is any body explain me why return current in three phase
power system is less then in a red, yellow, blue phases???
as we know Ir+Iy+Ib=In then why nutral wire has less then
phase current????

Answer Posted / s ray

The vector sum of three phase current is zero i.e neutral current is zero. but deu to load unbalance we get a small neutral current

A 100 kVA , 400 v/250 kv testing transformer has 8% leakage reactance and resistance on 100 KVA base . A cable has to be tested at 500 kv using the above transformer as a resonant transformer at 50 hz . if the charging current of the cable at 500 kv is 0.4 A find the series inductance required . Assume 2% resistance for the inductor to be used and the connecting leads . Neglect dielectric loss of hte cable . what will be the input voltage to the transformer ?
