| 摘 要： | 讨论了线路杆塔工频接地电阻测量方法，通过现场用接地摇表法（三极法）和钳表法对不同地形、不同电压等级线路杆塔接地电阻测量对比，发现钳表法测量误差极大，且误差元规律可循，无法修正，必须引起同行们的高度重视。通过对比，认为三极法测量比较准确。

| Abstract: | The methods to measure power-frequency ground resistance of transmission line towers and poles have been discussed.Comparing the ground resistance measurements of different topographic position and different voltage level by using ground megger(3-pole method) and clamp meter in the site,it is found that the measuring error of clamp meter is great and the error has no regular pattern to be followed and cannot be corrected,so much attention should be paid to these points.Through comparison,the measurement of 3-pole method is regarded as the more accurate one. |
