Document Type and Number:
WIPO Patent Application WO/2016/136053
Kind Code:
A1
Abstract:
Partial discharge occurring in a switchgear main body (1) is detected using a partial discharge detection sensor (11) that has a conductive layer (10) covering the surface layer of an insulating resin (8) covering the switchgear main body (1), a sensor conductor (12) having a periphery surrounded by the conductive layer (10), and a conductor pattern (13) connected between the conductive layer (10) and sensor conductor (12) and wherein the conductor pattern (13) is grounded at a commercial frequency and has a high impedance in a high frequency range.
