Cable Partial Discharge Mapping Service™

For non-destructive Partial Discharge (PD) site testing of HV and MV cables, the Cable PD Mapping service measures and reports on the health of high voltage cables.

The Cable PD Mapping Service™ is a fast, effective and accurate method of assessing the health of cables and locating the issues, without the need for expensive and inconvenient excavations.

Offline VLF Cable PD Mapping

For new installations, or when the customer can obtain an outage, our state of the art Very Low Frequency (VLF) Cable PD Mapping test equipment can be used to determine cable condition. EA Technology’s customised software allows us to accurately determine PD magnitude and location along the length of the cable. This allows the cable owner to manage their assets with increased confidence through recommendations such as regular monitoring and localised repairs to sections where discharge is found.

Our system is safe, non-destructive and has a 15-year track record of success from the UK and worldwide.
