Abstract
The paper presents a methodology for predicting the lifetime of metal-oxide varistor (MOV) which is widely used as a protective material in high-voltage equipment. The methodology is based on the characteristic time-current curve which is determined by the characteristic currents obtained from multistressed aging experiments. Results show that the proposed method is more effective and reliable than those adopted previously.
