Patents for on-line Partial Discharge Monitoring

We have used our expertise in on-line Partial Discharge detection, location and monitoring of medium and high voltage (MV/HV) electrical assets to develop a unique, patented solution – it’s application is available exclusively through HVPD.

As shown below, this application monitors the insulation condition of electrical motors which are located inside the hazardous Ex/ATEX zone – directly from the switchgear. In 2014, HVPD was awarded a Queen’s Award for Enterprise in the ‘Innovation’ category for developing this patented solution.

To date, patents for this application have been granted in China (ZL201280056292), UK (GB2509457) and the USA (9,581,632)
