Analysis Report of A Phase CVT Fault in 220kV Auxiliary Section I of 500kV Substation

An accident occurred in the substation due to a 220 kV voltage transformer failure that caused a bus differential protection alarm. This article comprehensively analyzes the cause of the failure based on the cause of the incident, the on-site test and inspection situation and the disassembly situation of the factory. The article comprehensively uses protection monitoring waveform analysis, infrared temperature measurement and field test to carry out failure mechanism analysis, and provides reference opinions for subsequent maintenance and repair of related products of the same type to improve equipment operation and maintenance level.
