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。
7 X- r& B% V8 m4 h在60065里10.3.2有规定8 h" R0 O5 x+ S u6 h5 U

short-circuited after the test voltage has been adjusted to the appropriate level, the output current is at

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.

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. |
