In the power system, transformer is one of the important equipments. Transformer condition hasa direct influence on the safety of the grid. Fault analysis and online monitoring of the transformer is the main means for monitoring transformer conditions. According to the online monitoring of transformer and related parameters, signal analysis, we can identify fault locations and the development trend of the problem, take timely measures for treatment, prevent the further expansion of the fault, and effectively improve the security of grid operation. This paper describes the common fault types of transformer, the advantages, research status, research content and methods of transformer online detection in order to provide reference for relevant personnel.
