| Abstract: | The different effects on over - voltage of transformer neutral point and zero - sequence impedance by the neutral point grounding and the reactance grounding are discussed and compared. On the basis of analysis and calculation, the author puts forward it is rational to ground 330 kV transformers by appropriate reactance. |

| Keywords: | transformer neutral point grounding reactance over-voltage zero -sequence impedance |
