摘　　要：介绍了台式继电保护装置传导骚扰测试的试验要求、试验布置和试验程序。以某继电保护装置传导骚扰测试超限值为例,通过分析使用人工电源网络提取受试设备电源端口传导骚扰的原理和实质,提出了针对传导骚扰测试超限值的整改措施和方法,并通过测试验证了整改措施的效果。Introduction was made to the requirements, arrangement and procedure of conduction emission test for the desktop relay protection device. Taking a relay protection device which didn’t pass the conducted emission test for example, this paper proposed the rectification measures and methods aiming at the above threshold of the conducted emission test by analyzing the principle and substance of artificial mains network （AMN） which picked up conducted noise from equipment under test （EUT）. The effect of the rectification measures passed verification.
