Switchgear partial discharge detection

Transient Voltage:By placing a capacitive coupling sensor on the grounded metal enclosure of the switchgear to detect the amplitude of partial discharge and the number of discharge pulses, determine whether partial discharge exists and its size.

Ultrasonic Partial Discharge Detection:By placing an ultrasonic sensor on the outside of the equipment, coupling the ultrasonic signals generated by partial discharge in power equipment in the air, to determine whether partial discharge exists, its size, and its location.
