Electricity Transmission Networks
SSEN continues to develop an extensive Transmission Network to support both generation and subsea interconnectors. As a consequence, the population of cable assets operating at 132kV continues to increase, generally all of which are extruded XLPE. Cable failure at 132kV and above, although uncommon, is extremely costly due to the necessary repairs and potential loss of network capacity. Unanticipated cable failures can occur due to a lack of routine maintenance which for cables generally consist of pressure testing to detect any defects.
To learn and understand new testing and diagnostic approaches for electricity cables operating at 132kV and above, recommend preferred methods and create an implementation strategy for the business.
