The withstand voltage is the level the equipment will withstand for a given length of time or number of applications without a disruptive discharge occurring, i.e. a failure of insulation resulting in a collapse of voltage and passage of current .

• 耐受电压是对于给定时间长度和加压次数,设备能耐受而不损坏,即无绝缘损坏引起电压崩溃和电流流过的电压。
