The scope of the project covers the installation, evaluation, and compatibility of new-to-market sensors for partial discharge in HV Cable. The reason this project is innovative is because this work has never been done before. National Grid have been offered a service from one manufacturer, whose kit is being tested, however this is on a stand alone platform without integration into the existing condition monitoring system. Therefore, National Grid are going to test the core technology and try to incorporate into the SAM programe.

To be able to provide online PD information on HV cables installed on the Transmission system.

This project will be successful if National Grid can quantitively monitor PD on HV cables.
