| Abstract: |
| By analyzing on zero sequence protection oftransformers,this essay gives a pilotstudy onthe prob lem ofover voltage at neutral point of 110 kVtransformers,the neutral point grounding type control and the safety problem in the design ofzero sequence protection of110 kVtransformersin Xiamen area.It provides a solution by removing some neutral point gapsto improvethe matching ofzero sequence protection on a trans former. |
| Key words: transformer,neutral point,zero sequence protection |
