Studies show that over 85% of disruptive failures in high voltage (HV) and medium voltage (MV) equipment are Partial Discharge related. Partial Discharge (PD) activity provides evidence of deterioration in assets, which can propagate and increase, until the insulation is no longer able to withstand the electrical stress therefore leading to flash-over and finally equipment failure. Therefore, early detection …
