摘　　要：在变压器首端施加不同波形冲击电压时,变压器中性点暂态过电压的实测值和计算结果表明,在波头较陡、波长较长条件下中性点过电压较高;反之,过电压则较低。Measured and calculated transformer neutral point transient over voltages related to incoming impulse voltages on inlet side indicated that the steeper the wave front and the longer the wave length, the higher neutral point over voltage, and vice versa.

关 键 词：变压器 中性点电压 首端电压
