Recently, a kind of 110-kV transformer resistance decline defect was found during our routine preventive test of transformers in the Guangdong power grid. The number of defective transformers reached thirty. This phenomenon seriously threatened the safe and steady operation of the power grid. The analysis and treatment of this resistance decline defect were carried out. The key reason for this defect was confirmed. The insulating characteristics of insulating oil decreased. Aminopyrine is a kind of medicine used as an antipyretic analgesic. However, it was seldom investigated by the electric p...
