| 摘 要： | 高土壤电阻率地区杆塔接地电阻存在无法测出的问题。通过理论计算认为，高土壤电阻率导致辅助接地探测棒接地电阻过大，从而导致接地电阻仪失灵。提出的措施为：增加辅助接地探测棒的长度和直径、提高土壤含水量、使用食盐做降阻剂。现场试验的结果证明了该方法的正确性和合理性。

| Abstract: | The grounding resistance measurement instrument fails in high soil resistivity because the grounding resistance is too high of auxiliary grounding detection rod from the theoretical analysis. In order to improve the sensitivity of measurement instrument, it is proposed to increase the length and diameter of auxiliary grounding detection rod, enhance the water content of soil and apply salt for decreasing resistance. The correctness and reasonability of the proposed method are validated by field experiment. |

| Keywords: | high soil resistivity grounding resistance measurement ZC -8 grounding modes auxiliary grounding detection rod |
