Abstract

The proposed device for checking the service life of a group of switching units can be used for monitoring the service life of high-voltage circuit breakers in radial mains with one-sided power supply. The device provides a possibility to determine the linear dependence between the input signal and output signal of the mains short-circuit current detector and, as a result, increase the monitoring accuracy.
