Abstract
PURPOSE: To lessen a damage in the synchronous machine, when an internal fault is caused in the synchronous machine, by such means that with a thyristor converter made in an operation of power inverter as well as with a main breaker made tripping, the field switch be made tripping after a prescribed length of time.
