Abstract: This paper studied the characteristic amount and evaluation method of reliability in relay protection devices of power system, designing the highly accelerated life test method. The test results were got by the influence tests of environmental factors for several typical devices, so as to analyze the influence degree of different factors. The stress limit were selected for the highly accelerated life test of relay protection devices and discussion was made on the conversion method from the characteristic amount of the highly accelerated life test to the characteristic amount of normal environment.
Key words: relay protection device; highly accelerated life test; reliability
