Grounding grids
Grounding grids
(OP)
Dear members,
After having a multilayer soil model assume we want to analyze ground impedance, GRP, touch voltage and step voltage for a large ground grids(lets say 1000 m * 1000 m), are the following assumptions the only ones we need or are there any other assumptions?
1- All conductors belonging to a given electrode are not at the same potential. There are potential drop along conductors due to their self-impedance. This means that the conductors modelled are not assumed to be lossless.
2- The mutual inductance of conductors needs to be taken into consideration.
Thanks,
Reza
