| 摘 要： | 重点研究了接地装置测试仪抗工频干扰能力测试的方法,通过搭建试验回路,对多个厂家的接地装置测试仪进行了抗工频干扰能力测试,测试结果表明,不少厂家的接地装置测试仪抗工频干扰能力差,不能满足现场测试要求,因此,建议在仪器选购时,对仪器的抗工频干扰能力进行考核。

| Abstract: | This paper emphatically studies the testing methods of anti?frequency interference ability for grounding test instruments. By building a test circuit, grounding test instruments from a number of manufacturers are used to test the anti?frequency interference abili?ty. The test results show that grounding test instruments of many manufacturers have poor anti?frequency interference ability and can not meet the test requirements. It is recommended to check the anti?frequency interference ability of the instruments when purchasing the instruments. |
