Earthing Resistance Calculation

The calculation of earth (ground) rod resistances is one of the few instances where the North American and International standards have the same method of calculation. To simplify the calculation, I compiled the most commonly used formulas. As a note however, this does not include AC Substation Grounding as per IEEE Std 80 - IEEE Guide for Safety in AC Substation Grounding.
