Opening and closing of the contact points creates induced voltage.
触接点的开启与闭合产生感应电压。

The main control parameters of SRD are opening angle, turn-off angle, phase current and phase winding voltage.
SRD的主要控制参数有开通角、关断角、相电流和相绕组电压。

With the much higher operating voltages now in use the projected voltage transients or surges due to switching i. e. the opening and closing of circuit breakers, have become the major consideration.
