摘要: The results of an extensive study conducted using a computer program designed to determine grounding performance in two-layer soils [1,2,3,5] are described and discussed. A variety grid configurations soil conditions analysed detail. calculated resistances, step touch potentials summarized several charts which could be used conveniently for practical design purposes. obtained prove that general, conventional methods analysis, such as the IEEE 80 method [4] uses "Km & Ki" irregularity factors, fail predict accurately performance. Also, it is shown there certain and/or burial depth, lead optimum or mesh potentials. Finally, will considerably higher (or mesh) than other comparable alternatives.
