接地装置测试仪抗工频干扰能力测试分析

Test Analysis on Resistance of Power Frequency Interference of Grounding Test Instrument

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。

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 ability. 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.
