【Abstract】 Transformer bushing is an important part of transformer, and must have sufficient mechanical strength and specified insulation properties. This paper describes a typical supervision case about dielectric dissipation factor of transformer bushing exceeding the standard, analyzes the cause of the problem, points out the influence of ambient temperature on dielectric dissipation factor, puts forward the importance of accurately understanding and grasping the technical standard, and suggests that the signing of technical agreement must be rigorous, meticulous and clear, etc. Therefore, it can provide reference for the supervision and problem handling of similar equipment.更多还原
