The aging problem of vegetable oil has severely restricted the popularization and application of vegetable oil transformers. Adding antioxidants is the most recommended solution. At present, there is insufficient research on the micro-mechanism appli

Abstract In recent years, there have been many cases of transformer failures caused by corrosive sulfides. At present, research mainly focuses on the single sulfide dibenzyl disulphide, but few research on multiple sulphur or the oil‐paper hybrid i

Abstract The active sulphur compounds in transformer oil would react with copper wires and produce cuprous sulphides, which then attach themselves to the surface of copper wires and insulating paper, thus reducing the electrical performance of oil–

The problem of sulfur corrosion has seriously affected the safe and stable operation of the power transformers. Currently, adding passivators into the transformer oil is the most effective method to suppress the problem. However, no explicit provisio

Secondary arc is more severe in the ultra-high voltage (UHV) power grid. However, the mechanism for the generation process of secondary arc at the extinction moment of a short-circuit arc is not yet clear. It is of great theoretical significance and
