摘　　要：为了使得接地系统的接地电阻测试中电流线和电压线放线方式比较自由,通过理论推导,提出一种简便、实用的任意三角形补偿接地电阻测试方法。该方法通过对接地体注入大电流,测量接地体与多个任意布置的电压极之间的电压,推出接地体的真实接地电阻,同时还可获取现场土壤环境下的等值土壤电阻率。通过实测,验证了所提测量方法的可行性。In order to make the electrode of current and voltage line being free place,a new testing method is proposed through theoretical calculate,that is named triangle compensation testing method.The real resistance of grounding system will be calculated by placing more electrode of voltage,their situations may free.And equivalent soil resistivity in the field soil is also gained.At the end of this paper,the feasibility of the proposed method is verified by a testing example.
