SF6 Leak Action
01/12/2008
As part of National Grid’s vision statement we as a company are committed to “safeguarding our global environment for future generations” and as a significant area of pollution SF6 usage is a specific performance measurement and all usage is monitored and reported.
National Grid is reviewing new technologies and repair methods to reduce escapes and where appropriate these advances are being used to tackle leaks on licensed and unlicensed assets.
As part of the maintenance works undertaken by our site teams there is often the need to top-up customer owned SF6 insulated assets. Whilst this is not reported as direct usage by National Grid this does fall within the work of UKES and allows us to discuss significant leaks with our customers with a view to supporting repair works.
Repairs have been undertaken on behalf of Central Networks and RWE NPower in support of their efforts to reduce escapes and evidence our commitment to reducing SF6 usage.
