请叫高手指点UL244几点,或者内行帮忙翻译几句话,谢谢,再谢谢

关于绝缘耐压测试的

Anessentially is to be applied as noted in (a)--(c).

(a)    between each different type of primary circuit (for example,the input and output circuits of a control both of which are intended to be conductively connected to the branch circuit in the end application).

(b)    Between terminals of opposite polarity on a capacitor that is connected across the line

(c)   Across any other insulation or spacing involving a primary circuit that is required toreduce the risk of fire,electric shock,or injury to persons(for example,at the input and output terminals of an isolation device)


谁帮我分析下,这电压到底要加在哪个地方,第一点是什么电路?第二点是什么电容?第三点我连方向都摸不到

急啊,很急,    谢谢各位先,是UL244A里面的,我们的产品是遥控插座,郁闷。

a) For example, primary current (input L) and isolated secondary circuit;
b) For example, line-voltage current carrying parts(input L) and grounding G;
c) For example,at the input and output terminals of an isolation device;
