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.

The earthing resistance calculation is not displayed in the above box. Is it possible to mail me a sample calculation.
Thanks in advance
