Getting down to EarthA practical guide to Earth resistance testingTest Equipment Depot - - 5 Commonwealth Ave - Woburn MA 01801 Getting down to EarthIntroductionNothing is quite so common or abundantly available throughout the world as the Earth s soil. While you likely think of soil as something to be tilled for planting or to be excavated for a building foundation, it also has an electrical property conductivity (or low resistance) that is put to practical use every day in industrial plants and speaking, Earth resistance is the resistance of soil to the passage of electric current. In reality, the Earth is a relatively poor conductor of electricity compared to normal conductors like copper wire. However, if the area of a path for current is large enough, resistance can be quite low and the Earth can be a good conductor.
