ac is more dengerous to dc.becuse-dc have magnitude and
derection of current same but in case ac reverse .is fully
depend on rms value. dc ac 220 v means (220*root 2)=311 .so
ac is more effective

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 ?
