If single phase having 220v so why 3phase is440v.
Answer Posted / rajesh
Whrere 3 Phase Star connection
Line vlotage = root 3 * phase voltage
if line voltage (Phase to Phase) = 415V
then phase voltage (phase to neutral) = 415/(root 3)
= 240v

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 ?
