Since the fall of potential method (used for measuring ground grid resistance) and the 3 point method (used for measuring soil resistivity) are basically the same process, except one drives a ground rod and one uses existing grid; Is it possible to measure a substation’s soil resistivity using...
im not physically testing the ground resistance at this point, i will use fall of poential method after the substation is built. im estimating it now before i build it, the software im using will estimate the ground resistance with the grid i have designed in the soil at the location. I have...
im trying to determine the resistance to ground of a substation, the software im using gives two resistances, driving point and equivalent circuit shunt resistance, does anyone know the difference?
well if i model the slab connected to the grid it behaves just as you described, if i model the grid not connected the touch tends to be the very high in the middle of my slabs. IEEE 80 says that foundations most of the time are connected to the grounding system in someway. Just to be safe...
Does anyone know how to model a foundation in a substation using WinIGS. I am designing the grounding system and get very different results depending on how I model the foundation. I'm unsure if I should use the re-enforced concrete block electrode(electrically isolated since we will not connect...
