摘要
为了解决接地电阻检测仪在不良环境及不当操作的影响下,测量值往往偏离真值这一问题。文章在阐述接地电阻的组成以及接地体接地电阻的计算方法的基础上,分析了造成测量误差增加、影响接地电阻测量的多种因素。根据上述分析提出了采用物理方法,如深埋接地体至最佳深度等或采用降阻剂等化学方法来降低接地电阻。
Measurment ：esults often deviate from their true results when the earth resistance meter works in poor environments or impreper operation. In order to solve this problem, The composition-of the earth resistance and the calculation of the earth resistance of the resistance body connected with the ground were discussed, all kinds of factors that make the measurement error of earth resistances increased and affected were analyzed. The physic methods, for example, deepening earth resistance of body connected with the ground to the optimal depth, or chemical method, for example, resistance depressing dose method, to reduce the earth resistance were proposed.
