垂直分层土壤中接地电阻的测量及其误差分析

The Grounding Resistance Measurement and Error Analysis of Grounding System in Vertical Layered Soil

分析了垂直分层土壤结构中的接地系统接地电阻测量电极的布极规律及测量中可能产生的误差。提出了一种新方法—反向修正系数法 ,可供工程实际参考。

The arrangement rules of measuring electrodes, which areused to measure the grounding resistance of grounding system in vertical layered soil, are analyzed by a ring disk electrode. The measurement errors are analyzed in details. A new method which uses correction coefficient and can be used in practice is put forward in this paper.
