摘要
目前国内没有针对PLC电力猫的EMC测试标准,如果按照信息技术设备类标准将无法通过认证测试。结合欧洲PLC产品标准,对PLC电力猫的EMI测试和环境搭建问题进行系统性分析。辐射测试时,给出了场地方面的调整措施,以保证辐射测试顺利通过;针对传导测试的四个项目:测试非对称传导骚扰(电源部分)、动态功率控制、认知频率排除、非对称传导骚扰(信号部分),结合测试连接图,对限值及注意事项等进行了分析。
There＇s no EMC standard relevant PLC （Power Line Communication） product so far in local land. It＇s difficult to acquire CCC certification according to ITE （Information Technology Equipment）. So, we use European standard to analyze the environment and test method, some suggestions to improve EMI test method as below. To Radio Emission test, what we can do to ensure the result by adjusting the test environment. To conducted test, we can analyze the test TOP, the environment and the notes.
