摘　　要：接地系统是保证变电站和发电站电力输出稳定的重要设施,其不仅保障了电力供应的稳定,同时也能够保障周围工作人员的个人安全。接地电阻是接地系统中主要的数据指标,日常工作当中当电站的运行达到一定时间后就需要对其接地的电阻进行测量,当前国内接地电阻的测量方式存在一定的问题,测量引线长度过大容易受到外界电磁波的干扰,导致电阻值检测物产。因此应该采取短距测量方法,降低误差率,保证测量结果的准确性。文章对地网接地电阻短距测量方法进行研究,首先对短距测量技术进行了阐述,并介绍了利用空腹式接地降阻技术,以期能为相关工作提供参考。Grounding system is to ensure that the transformer substation and power plant power output stability of the important facilities, it not only guarantee the stability of the power supply, at the same time also can ensure the personal safety of staff. Grounding resistance is the main data index in the system, daily work when the operation of the plant reaches a certain time and then need to measure the resistance of ground, the current domestic grounding resistance measurement mode has certain problem, measuring the lead length too vulnerable to external electromagnetic interference, lead to resistance testing products. So you should take a short distance measuring method, reduce the error rate, ensure the accuracy of the measurement results. Articles on a fixed ground resistance short distance measurement method is studied, first explains the short distance measurement technology, and introduced the use of hollow grounding resistance reduction technology, in order to provide references for related work.
