Review on fault diagnosis of power transformer

Abstract

The power transformer serves as a vital apparatus in the power system, with its steady function being significantly essential for the fluid execution of voltage conversion and distribution. The efficiency and precision of fault diagnosis methodologies can substantially aid in maintaining the consistent and stable operation of the transformer. This paper addresses the progression of transformer winding monitoring technology, touching upon the current investigative status concerning data purification, monitoring parameter forecasting, and the fault diagnosis model amidst the transformer fault diagnosis. It is imperative to fortify the research direction of transformer fault diagnosis technology in forthcoming future endeavors. Delving more profound into the realm of transformer fault diagnosis research has substantial implications in bolstering the efficiency and precision of fault diagnosis, thereby enhancing the operational stability of power transformers.
