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 ?
The inventer is a battery, but if lost current at home u will turn on the fan but the is AC and inventer battery is dc . Then how the fan was rotating. What device Or machine in fan converst the Dc power to Ac power
