1.Multiple reignition makes the frequency and amplitude of overvoltage increase and might do harm to transformer coils by cumulative effects for its surge steepness.
多次重燃使得过电压频率幅值均升高,会对变压器等绕组型设备绝缘造。
2.It is showed that magnetic rings of amorphous material on a conductor can notably increase its inductance and make effective suppression on the steepness of the vacuum restriking overvoltage.
