ActiveInsulated bushings - Guide for the interpretation of dissolved gas analysis(DGA)in bushings where oil is the impregnating medium of the main insulation(generally paper)
绝缘套管 油为主绝缘（通常为纸）浸渍介质套管中溶解气体分析（DGA）的判断导则
Application Summary AI generated
This standard provides guidelines for interpreting dissolved gas analysis (DGA) results in oil-impregnated paper-insulated bushings used in high-voltage electrical equipment. It is applied by power utilities and transformer manufacturers to assess the internal condition of bushings, detect incipient faults such as partial discharge or overheating, and determine whether a bushing requires maintenance or replacement. The standard is specifically relevant for bushings where oil serves as the primary impregnating medium for the paper insulation, commonly found in power transformers and circuit breakers.
