摘　　要：针对桩基础杆塔接地引线无法断开,现有测量装置无法准确测量其接地阻抗的实际问题,提出了一种基于电流传感器的三极法测量方案,并研制出相应测量装置。现场测试数据表明,该装置与传统装置一致性良好,能较好地对桩基础杆塔接地阻抗进行测量,测量精度满足工程要求。For the practical problem that pile found ation tower grounding conductor can not be disconnected and existing measuring device can not accurately measure the grounding impedance, this paper proposes a three-electrode method measurement scheme based on current sensor, and develops a corresponding measuring device.The field test data show that the device has a good consistency with the traditional device and good measurement result for pile foundation tower grounding impedance,the measurement accuracy meet the project requirements.
