部分放電検出装置、部分放電検出方法、部分放電検出システム及びコンピュータプログラム
Document Type and Number:
Japanese Patent JP7273482
Kind Code:
B2
Abstract:
To provide a partial discharge detection device, a partial discharge detection method, a partial discharge detection system, and a computer program that can remove noise with higher precision.SOLUTION: A partial discharge detection device according to an embodiment has a signal acquisition part, a noise signal storage part, and a noise removal part. The signal acquisition part acquires a mixture signal of a partial discharge signal representing a signal of a partial discharge generated in a box body accommodating electric equipment and a noise signal representing a signal of noise generated nearby the box body. The noise signal storage part stores a past noise signal representing a signal of noise acquired before the partial discharge is generated nearby the box body. The noise removal part acquires a restoration signal having the noise signal removed by removing the noise signal from the mixture signal based upon the mixture signal and the past noise signal.SELECTED DRAWING: Figure 1
