| Abstract |
The bar-shaped electrode is very popular in earth construction for its easy obtainments of the regulative grounding resistance values on power distribution systems in many countries. For these reason, a lots of researches are being proceeded on its deformation and materials. But the grounding construction has limit for improvement the grounding resistance characteristics not only by the improvement of the driven electrode, because that the grounding characteristics are very sensitive to soils(hard, soft). This study is about the construction methods on which the driven electrode can be serially or parallely connected using by hollow screw rod for obtaining the regulative grounding resistance values. The experimental results show that the grounding resistance values are reduced more than 30[%] comparing with the other construction methods under the same conditions(earth resistance, numbers of driven electrode, construction method of serial and parallel, chemicals for reducing grounding resistance, water). |
