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.
