SWITCHGEAR PARTIAL DISCHARGE (PD) MONITORING

We offer non-intrusive real-time detection of partial discharge in all the components of a Switchgear unit i.e. instrument transformers, cable termination box, busbar, circuit breaker truck and spouts. We also distinguish between real PD and interference i.e. noise, vibration etc allowing you to make informed decisions while saving cost and improve the safety of your network, operator and public.


Our partial discharge experts will interpret the results and provide strategic recommendations for corrective measures.

We use transient earth voltage (TEV) capacitive sensor to detect internal void discharge and ultrasonic microphone to listen to the surface discharge activity.
