HRC means High Rupture Capacity
If during starting time of any motor,it will draws maximum 3times of rated capacity,
So Fuse want to withstand that much heavy current during starting time,its only of Short time intervel.

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 ?
