Answer Posted / satheesh kumar
In all cables insulation is important.since the voltage is
the factor which is produce current in a
system.i.e.=V/R=I.So to avoid heavy leakage current(when the
system is having insulation in MOhms)R must be
important.i.e.insulation.When ever the leakage current
becomes heavy it is called short circuit and due to failure
of insulation.So Voltage is the factor to be considered for
protection of cables or any other equipment for safety.thus
insulation in more in high volatge cables.

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 ?
