PARTIAL DISCHARGE DETECTION PROBE, PORTABLE PARTIAL DISCHARGE MEASUREMENT DEVICE AND MEASUREMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide a portable partial discharge measurement device with high measurement sensitivity.;SOLUTION: When a casing 1 is made of a non-conductive material, high frequency electromagnetic waves 4, 5 generated by partial discharge 3 propagate from an insulating material 2 of an electric/electronic device through the casing 1 to outside of an outer wall thereof. Partial discharge high frequency electromagnetic wave detection probes 6, 7 of a portable partial discharge meter 8 act as an antenna and allow the portable partial discharge meter 8 to receive the high frequency electromagnetic wave generated by the partial discharge and display a value corresponding to a measured value. The high frequency electromagnetic waves 4, 5 generated by partial discharge are directly detected from the outer wall or by approaching or being in contact with an insulating material 2 of an electric device regardless of whether a casing is made of a conductive or non-conductive material.;COPYRIGHT: (C)2015,JPO&INPIT
