Modern Relay Protection & Control Applications


The advent of microprocessor based relays has brought about significant efficiencies in design and options available for types of protection all in a single relay. Further insight to detailed design for improving reliability and understanding of power systems can be realized with intricate event monitoring and use of user defined logic in these relays to achieve this end. This presentation will examine specific field examples and commissioning results of such applications.
