Abstract
Analysis of the features of remote methods for detecting partial discharges in high-voltage insulation and the possibilities of their simultaneous use
Incoming article date: 02.04.2024This study examines the combination of several non-destructive partial discharge (PD) detection methods to improve the accuracy of their detection. An analysis of methods for detecting PD in high-voltage insulation, a consideration of their features, and an analysis of the possibility of combining them to achieve the most accurate measurements were carried out. Analysis of the practical effectiveness of combining methods based on the developed variations of installations operating on the principles of two or more detection methods. Options for installations for PD detection that combine two or more detection methods are considered. A conclusion is given about the possibility of combining various methods of detecting partial discharges, taking into account the peculiarities of this type of combination. The simplest and most effective at the moment is the use of measuring cells that combine electromagnetic and acoustic detection methods.
