Applicability of oscillating wave test system for on-site PD diagnosis of high voltage power capacitors


Most of the aged high-voltage (HV) power capacitors are the oil-immersed paper capacitors in Japan. Hence, it is necessary to establish an on-site partial-discharge (PD) diagnosis of the oil-immersed paper capacitors. The capacitance of the capacitors is very large, so it is difficult to apply HVAC to the capacitors. Therefore, it is difficult to perform… (More)
