Abstract:The fault of multipoint grounding is one of the faults occurred frequently in a transformer and the fault reason and its features are analyzed in this paper.The diagnosis method,combining the electrical experiment with the chromatography,and the fault treatment method according to the real situation are introduced too and finally,one real falt example is analyzed according to the falt chromatography result in a main transformer.
Keywords:transformer  iron core  multipoint grounding
