摘　　要：本文给出了4台220kV变压器首端进波中性点电压的测量结果,提出了计算变压器中性点暂态电压响应的数学模型,在该模型上的计算结果与实测结果一致.This article gives the measuring result of the voltage at the neutral point of impulse wave on the head of winding of four 220kV transformers and puts forward a mathematical model for calculating the transient voltage response at the transformer 's neutral point. The result of the calculation at the model is identical with which of the practice measurement.
