Abstract
This paper includes new protection concepts and practices to avoid mechanical damages of three-phase transformer by asynchronous operation of synchronous generator. This failure is often caused just after synchronous generator was connected to the grid because of a malfunction of the controller or misconnections of the synchronous devices. The results of the studies on the analyzing the phenomenon of asynchronous operation experienced in Korea and rapidly detecting asynchronous state are described.
