PARTIAL DISCHARGE DETECTION TEST LINK, PARTIAL DISCHARGE DETECTION SYSTEM AND METHODS FOR DETECTING PARTIAL DISCHARGE ON A POWER CABLE

摘要

A partial discharge detection test link (20) and system detect partial discharge of a power cable at a power cable accessory (6). The partial discharge detection test link (20) is a permanent or temporary substitute for a conventional service link, connects directly across the power cable accessory and includes a conductor member (22) and a partial discharge sensor (24). The conductor member (22) has an electrically conductive element (26) and an insulation (28) surrounding and extending along the electrically conductive element. The electrically conductive element (26) is electrically connected directly between the first and second accessory components. The partial discharge sensor (24) is disposed about the conductor member (22) and has the electrically conductive element as a primary winding and a secondary winding with the insulation positioned between the primary and secondary windings.
