摘要：

This paper discusses the goals of routine maintenance testing for protective relays. The paper advances a Markov Probability model that predicts the optimum test interval for protective relays with and without self-testing capabilities. The model uses known system transition rates and relay failure rates. The probability model shows that the optimum test interval for a relay with self-tests is quite long.
