谈谈钳形接地电阻测试仪的使用

Applications of the Clamp Grounded Resister Tester

介绍了钳形接地电阻测试仪的测试原理,即在测量时必须要有一个供电流流过的有效的闭合回路。根据各局站的不同情况,分析了该仪表在使用中存在的问题,并介绍一种可行、实用的测量方法。

It describes the measure principle of the clamp grounded resister tester, that is,a effective close loop for current flow is necessary when doing the test. On the basis of various situation in many offices or stations, it analyses the problems of the tester in its practice applications, and presents a feasible and practicable measure method to settle the above problems.
