Condition-based Management of Electrical Assets

A comprehensive range of on-line partial discharge (OLPD) test and monitoring technology for in‑service condition assessment of individual assets and complete networks operating at 3.3 kV and above. Suitable for MV, HV and EHV assets, our technology gives an early warning of developing faults in the insulation, helping to avoid costly failures and unplanned network outagesOur 4‑Phase Asset Management Approach provides for a systematic and cost effective methodology which can identify, locate and monitor PD activity within the customer's network.


Complete Network Monitoring

HVPD's condition monitoring solution provides an early warning of incipient HV insulation faults, helping network operators to avoid unplanned outages. 



PD can occur in any MV or HV cable operated at 3.3 kV or above. Our testing can locate potential failure sites to within 1% of a cable's overall length using the technique of On-line Cable Mapping.



Our OLPD test and monitoring technology can identify dangerous PD activity in AIS/GIS/SIS-type switchgear rated from 3.3 kV and above, and monitor any further insulation deterioration caused by such activity.



OLPD screening can detect dangerous discharges that emanate from the main windings and bushings of in-service transformers rated at 3.3 kV and above, and from the transformer accessories.

Motors and Generators

OLPD testing is widely accepted in the oil and gas and power generation industries as the best way to assess the stator winding condition of motors and generators from 6.6 kV to 30 kV.
