Abstract

The insulation problem of power equipment is one of the main reasons for power equipment failure. The insulation condition of power equipment can be judged in advance by monitoring partial discharge. It is of great significance to realize on-line monitoring of partial discharge defects in time and effectively, and to monitor the real-time status of transformers and conduct fault analysis based on them. Acoustic detection methods are widely used due to their good non-destructive properties. When a discharge fault occurs inside a transformer, it generates rich acoustic signals during the specific process from severe defects to faults. By monitoring the acoustic signals, it provides auxiliary basis for power grid dispatchers to make decisions. In this paper, the application status of audible acoustic sensor and optical fiber acoustic sensor in transformer partial discharge is summarized. Transformer partial discharge monitoring technology based on acoustic sensor is a relatively new transformer fault diagnosis method, which has great research significance. This study provides a good theoretical basis and practical guidance for partial discharge online monitoring.
