Title:
ELECTRICAL DISCHARGE DETECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/228619
Kind Code:
A1
Abstract:
Provided is an electrical discharge detection system for detecting output of noise superimposed on voltage or current in an electrical circuit to which a load is connected, the electrical discharge detection system having a configuration comprising: a filter unit capable of extracting an output waveform in a specific frequency band; a division unit capable of dividing a certain period of time into a plurality of segments; and a determination unit capable of determining the degree of continuity of segments where output of noise has been confirmed, or of comparing output of noise between segment groups, each of which is a collection of a plurality of segments.
