Abstract

PROTECTIVE relays are intended to protect expensive electrical equipment. With proper care they will perform this duty, but when neglected they may become inoperative and could become a hazard in themselves. Since the reliability is the most important quality of protective relays it follows that their maintenance must be first class.
