if 50hz transformer is required to be run on 50% frequency
what needs to be done???????????

Answer Posted / pankaj rajput

It will trip on over fluxing protection, if the protection
is installed.

It's not a wise situation to connect transformer to a lower
frequency with same voltage. The flux induced in core is
directly proportional to voltage & inversly proportional to
frequency. Hence the core will be over heated/over fluxed
and may get damage due to over heat.

The only remedy is reducing the voltage in same ratio.

how does the terminal voltage of transmission lines increase when a capacitor is connected???? This happens not only in transmission lines but also in all circuits. How??? When a capacitor is connected in a transmission line, capacitor also takes energy from the same supply. But how is it able to increase the terminal voltage??? Practically What sequence of events happen during increase in voltage???

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 ?
