Partial Discharge Testing

The detector Kit is a portable partial discharge detector which detects both surface and internal discharge activity within medium voltage equipment.

Partial discharge activity causes insulation material to deteriorate and eventually leads to failure of MV equipment. With the Ultra TEV Partial Discharge Detector, surface discharge is detected using an ultrasonic sensor and internal discharge is detected using an electromagnetic sensor which can detect transient earth voltages or TEV’s. All tests are carried out without the need for an outage.
