| Abstract: |
| Combined with various over-excitation situations happened in the operation of 500 kV transformer, the principle and performance of ABB over-excitation protection is analyzed. The drawbacks in the complete matching of the protection characteristic with the over-excitation capacity of Mitsubishi transformer at some points is indicated, and some improvement suggestions are put forward. |
| Key words: main transformer,over excitation protection,characteristic curve of over excitation, |
