Computation And Measurment Of The Resistance Of Grounding Grids Buried In Two-Layer Soils

It creates the model of layer soil by using the CDEGS software, analyses the resistance error which is measured by traditional three-poles way, measures the grounding grids resistance and soil resistance rate of Hejin Power Plant, creates the electromagnetic model of layer soil and grounding grids model of Hejin Power Plant, calculates the step voltage > touch voltage N voltage distribution of earth surface in fault of Hejin Power Plant. In the end, it compares the measuring value and calculating value of grounding grids resistance in Hejin Power Plant.Yang JieSupervised by Prof. Cui Xiang, Cheng Xue-ming...
