An adaptive fault diagnosis method of power transformers based on combining oversampling and cost‐sensitive learning

Abstract Dissolved gas analysis is an important technique for the insulation condition assessment and incipient fault diagnosis of power transformers. However, the performance of the traditional ratio methods can be hardly improved due to the overreliance on absolute ratio threshold. In this paper,...
