Abstract
The grounding resistance of the tower is the main parameter to measure the grounding safety performance of the tower. As a commonly used method of measuring the grounding resistance of the tower, the clamp meter method has certain errors in the measurement principle. Based on the measurement principle of the clamp meter method, the artificial grounding device, tower foundation, transmission line tower and lightning protection wire are modeled and simulated, and the influence of different factors on the error of the clamp meter method measurement of the ground resistance of the tower is studied. The calculation results show that the change of soil resistivity has the most obvious influence on the calculation results. The higher the soil resistivity is, the coefficient of transformation between the measurement results of clamp tab. Method and the actual value gradually decreases. In the case of multi base tower grounding, the measured transformation ratio coefficient will be smaller than that in the case of single base tower grounding due to the shunt of tower lightning line parallel branch; The shorter the span between towers or the lower the height of towers, the smaller the parallel equivalent impedance of tower lightning line branches and the smaller the transformation ratio coefficient.
