Abstract: In allusion to the condition that the mean operating time between failures (MTBF) of relay protection equipment was confused with the life of relay protection equipment, this paper explained the definition of the MTBF index and presented three different methods for the calculation of the MTBF index of relay protection equipment, including reliability prediction, reliability test, and site failure data statistic, then analyzed the relationship between the MTBF index and the life of relay protection equipment, and raised the recommended values of the MTBF index at last.
Key words: relay protection; mean operating time between failures; standard
