Earthing Grid Resistance IEEE Std. 80 Calculator
This calculator produces the grid resistance within a substation based on several parameters such as total buried length of conductors, area occupied by ground grid and the depth of the grid.
The equation is based on the IEEE Guide for Safety in AC Substation Grounding (IEEE Std 80-2013), section 14.2, equation 57 and essentially combines the resistive properties of a metal plate, conductors and the depth at which it is buried.
