Partial Discharge Inspection Test Series HZJF-90V1Switch Cabinet Partial Discharge Detector Partial discharge (PD) is the symptom and manifestation of insulation deterioration of power equipment, and also the cause of further insulation deterioration. Because the result of insulation breakdown is often serious, so the partial discharge detection of power equipment is particularly important. Partial discharges of electrical equipment are electrical discharges that do not completely short-circuit the electrodes. Such discharge amplitudes are usually small, but they can cause a continuous decline in insulation, which can lead to eventual failure. Live partial discharge detection provides a fast and easy way to identify potential insulation failures that could cause power outages or personal injury.
