Multiple reignition makes the frequency and amplitude of overvoltage increase and might do harm to transformer coils by cumulative effects for its surge steepness.

燃使得过电压频率和幅值均升高，会对变压器等绕组型备绝缘造成危害。

This paper describes the mechanism that multiple reignition of breaker can restrain or increase progressively the switching-overvoltage during switching off inductive or capacitive load.

论述了开关在开断感性或容性负载时燃对过电压的抑制或递升机理。
