Abstract

The integration of control and monitoring functions into microprocessor based protection relays continues to escalate as new relays are introduced. Adaptive relay algorithms are also being applied. This paper explores this trend regarding a multiprocessor-based transformer protection and management relay intended for use on all sizes of power transformers. The benefits of several unique adaptive algorithms are discussed. A flexible user-selected approach to harmonic restraint is described
