In addition, the impulse loads caused voltage wave and flink, and lopsided loads caused imbalance of three - phase voltage. 另外，电力系统中的冲击负荷也引起电压波动和闪变，不对称负荷引起三相电压不平衡。
The coefficient of grounding is the ratio of the maximum sustained line-to-ground voltage during faults to the maximum operating line-to-line voltage. 接地系数是故障时最大持续相电压与最大运行线电压之比。
