A discussion on the reliablilty of static relays is made in this thesis , because some new problems have arisen after static relays are applied on the relay protection of electric system .
The article discusses about the proper selection of staticrelay test points through introducing the contactor sketch of rectifying static relays with digital dial switches and easy-happening faults.
