Methods of measurement of touch-current and protective conductor current

信息技术设备中保护连接导体电阻的测量方法

Test Method and Appliance of Protective Bonding Conductor about the Information Technology Equipment

介绍了型式认可试验和工厂例行检验中有关信息技术设备的保护连接导体电阻的测量方法，以及在某些特殊设备上的应用。

The text introduced the test method and application in some special instances about Information technology equipment Protective Bonding Conductor in Type test and Routing test .

所以保护接地导体是不用测试的。

PROTECTIVE EARTHING CONDUCTORS are considered to comply without test .

但在某些情况下，用电负荷增加时线路过负荷保护却不能避免导体超过最高运行温度。

However , in some cases , the over-load protection cannot avoid that the conductor exceeds the maximum operating temperature when the electrical load increases .
