Title: PARTIAL DISCHARGE SENSOR
Abstract:
The configuration of the invention provides a metal case (7) positioned on the outer part of flanges (2a, 2b) and, inside the metal case (7), a bow-tie antenna (8) positioned in a direction orthogonal to the circumferential direction of the flanges (2a, 2b), whereby a partial discharge sensor for the high sensitivity reception of signals arising from partial discharge across a wide bandwith can be obtained.
