Partial discharge (PD) can pose a significant threat to high voltage electrical equipment and they are also typically the first indicator that an electrical asset is degrading. If left undetected or if reparative actions are not taken, partial discharges can lead to costly electrical failures. In the post we will examine a case study on the benefits of PD Monitoring.

High voltage circuit breakers are critical to the safety and effective operation of the electrical system. A circuit breaker must react quickly when a fault occurs to isolate fault currents from the rest of the system. While much attention is given to the monitoring of transformer conditions, circuit breakers are by far the largest contributor to the occurrence of substation events.
