The load throw-off may result in run-away speed being equal
to twice the normal speed ,hence the voltage may also become
twice. Over voltage relay should be set at not more than
120%.You can employ the AVR so that the voltage does not
increase with the speed.

According to ohms law voltage proportional to current, then why should current rating is low with high voltage rating in transformer?
