Summary

Relay models have been used for performing a variety of protection studies. It started with the practices of building prototypes, a practice which remained in use when solid state technology was introduced in manufacturing protection relays and continued even after the introduction of digital electronics technology. Gradually it was replaced by using computer programs that modelled the performance of relays, which purpose was to study the impact of the operation of relays on system performance. Models of relays are now being used in designing relays, analysing system performance and studying the impact of relay operation on system security.
