摘　　要：常用的杆塔接地阻抗测试方法有三极法(放线法)、钳表法(免放线法)、回路阻抗法(免放线 法)、免拆线法。分析这几种方法的优劣并对每种方法的适用范围,并进行总结。There are commonly used methods for measuring tower grounding impedance include three-pole method (wiring method), clamp meter method (wiring-free method), loop impedance method (wiring-free method), and wiring-free method. In this paper, the advantages and disadvantages of these methods are analyzed, and the application scope of each method is summarized.
