Use of Software for Calculations of Earth Electrode by Empirical Formulas and by an Analytical Method
Jagdish Kumar Arora · Tunnelling and Underground Space Technology · 2008
Very often a computer program is used to compute earth resistance and step and touch voltages of a grid earth electrode; the programs used for such calculations are computer coded formulas given in IEEE Std 80. To analyze the performance of an earth electrode, another type of software is used. Such a software uses a network representation of an earth electrode. A basic dc network consists of self and mutual resistances. This paper brings out the principle aspects of the two methods.
