| 摘要 |
A partial discharge signal processing device of the present invention is provided with: a partial discharge signal receiving unit 1 disposed inside a high voltage electric device; a partial discharge signal processing unit 2; and a coaxial cable 3 connecting the partial discharge signal receiving unit 1 and the partial discharge signal processing unit 2. In addition, the partial discharge signal receiving unit 1 comprises an electromagnetic wave receiving unit 1a that receives electromagnetic waves generated by partial discharge. Further, the partial discharge signal processing unit 2 comprises: a detection unit 2a that detects a partial discharge signal transmitted through the coaxial cable 3; a band limiting unit 2b that limits the frequency bandwidth of the partial discharge signal; an attenuation amount correction unit 2c that corrects an attenuated partial discharge signal; and a signal output unit 2d that outputs, to an external device, the corrected partial discharge signal. |
