Reliability of microprocessor-based relay protection devices - myths and reality

Malfunction of relay protection is one of the main causes of the serious failures that periodically occur in power systems all over the world. According to the North American Electric Reliability Council [1] in 74 % cases the reason for heavy failures in power systems was the incorrect actions of relay protection in trying to avoid the failure. Thus the reliability of a power system depends on ...

Reliability of Microprocessor-Based Relay Protection Devices: Myths and Reality

The article examines four basic theses about the ostensibly extremely high reliability of microprocessor-based relay protection (MP) touted by supporters of MP. Through detailed analysis based on many references it is shown that the basis of these theses are widespread myths, and actually MP reliability is lower than the reliability of electromechanical and electronic protective relays on discr...
