“…When predicting the service life, we should try our best to exclude the influence of external interference factors and human factors in order to obtain more accurate and reliable results. The service life of the relay protection device can guide the development, design, processing, creation and maintenance of the device [8][9]. Due to the rapid upgrading of relay protection devices and the variety of products, the service life of relay protection devices can not be well determined.…”

“…The methods proposed in References [19][20][21][22][23][24] do not require the identification of the traveling wave head, and their measurement time scales are large enough. Therefore, we classify this method as a failure analysis method.…”

“…Therefore, we classify this method as a failure analysis method. Among them, References [19,20] built transmission equations to identify the fault location, based on different frequency components of voltage and current, while References [21,22] identified the fault location based on the same frequency (IF) component of both the voltage and current. Reference [23] obtained the voltage expression of the fault point from both ends and acquired the fault distance based on the equality of the calculation results.…”
