Question

b)
A 100 KVA, 250V/1200KV feed Transformer has a resistance and reactance of
1% and 5% respectively. This Transformer is used to test a Cable at 400 KV 50
Hz the cable takes a charging current of 0.5A at 400 KW. Determine the
series inductance required. Assume 1% resistance of the inductor. Determine
the put voltage to the transformer. Neglect the dielectric lose of the cable.​

Answer 1

Explanation:

A 100 KVA, 250V/1200KV feed Transformer has a resistance and reactance of

1% and 5% respectively. This Transformer is used to test a Cable at 400 KV 50

Hz the cable takes a charging current of 0.5A at 400 KW. Determine the

series inductance required. Assume 1% resistance of the inductor. Determine

the put voltage to the transformer. Neglect the dielectric lose of the cable.
