Answer Posted / nithi

if u connect the voltmeter in series, there is no power to
the later stages (like the source having high internal
resistance).
if u connect the ammeter in parallel,there is a dead
short circuit of the source(if fuses used,blown-off &
chance of ammeter coil damage).

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 ?
