The APD Series High-Voltage Switchgear Partial Discharge Monitoring Device monitors the number and frequency of local discharges in switchgear cabinets in real time by detecting the electromagnetic wave radiation generated by local discharges. It evaluates the insulation condition of electrical equipment and detects potential faults, providing early warning to avoid failures.
