¿µ¹®³»¿ë¿ä¾à This standard provides various types of grounding resistance calculation formulas before installation of electrodes which are standardized. The calculation methods are applied as to the types of grounding electrodes. So the types of grounding electrodes are in the first step classified. And then applicable calculation formular is provided to them.
