补充楼上:标准里面的100mA,200mA是对于设备的要求,并非判断测试结果的判据。1 K- X8 n& C/ H
在60065里10.3.2有规定
: `) v. B: ?' G/ U# e: CThe test voltages shall be obtained from a suitable source so designed that, when the output TERMINALS are

least 200 mA.
2 \+ n9 C, G, B; U3 `An over-current device shall not trip when the output current is less than 100 mA.
: X' H z3 s2 _6 I, h! g试验电压应该由合适的电源提供,该电源的设计应保证当试验电压调节到相应的等级后,短路输出端子时,输出电流至少为200 mA.
* _( \) D( _" Y( {$ J当输出电流小于100mA时,过流装置不应该打开。

所以一般来说,如果是65的规章,耐压测试机不能直接接到市电上, 必需用隔离变压器的source提供power. |
