Abstract

The system and process for monitoring the degradation of surge arresters not connected to the electrical system consists of a support structure for circuit connection to the surge arrester, allowing a power supply unit, controlled by an electrical variable control unit, to deliver power appropriate to the surge arrester specifications added by the user to the system via data input devices. While power is being supplied to the surge arrester, electrical variable monitoring devices measure appropriate parameters and transmit real-time data to a processing unit. The processing unit then calculates and evaluates the surge arrester degradation, displaying the results to the user via a display unit. This support structure includes protective devices to prevent hazards from potential leakage currents while power is being supplied.
