| Objectives | 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 quantitatively monitor PD on HV cables. | |
| Abstract | National Grid has many kilometres of underground HV cable either approaching or exceeding its design life. More information is required to be able to optimise replacement, avoid failures and reduce costs while still managing risk to the Transmission System. There has been little work completed in the area of online monitoring of HV Cables due to the complexity and lack of viability to retro-fit sensors. This is due to oil filled cables being designed to be closed loop, both electrically and hydraulically, for life. The capture of a signal is also complex due to the nature of Transmission cables being longer and having attenuated signals. The problem that National Grid face is that there is no proven methodology for online condition monitoring of HV cable currently available. Development The method proposed involves evaluating new sensors for application on the HV Cable system in the Transmission Network, and developing 2 systems that are able to monitor in a remote and harsh location. From there, National Grid are going to investigate the compatibility of the sensors with the existing SAM system. This solution will then provide a means of evaluating cable condition for optimised capital replacement and risk mitigation.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
