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 ?

Dear sir, my knowledge about cable size determination is limited. Though I read examples I could not calculate the Cable size required for electric driven pump 40 KW, 380 Volt, 50 HZ, 50 meter from transformer and it is three phase star delta starting. Please help as there is no one in my surroundings to help.
