In electricity supply systems, an earthing (grounding) system defines the electrical potential of the conductors relative to that of the Earth's conductive surface. The choice of earthing system has implications for the safety and electromagnetic compatibility of the power supply.or measurement purposes, the Earth serves as a (reasonably) constant potential reference against which other potentials can be measured. An electrical ground system should have an appropriate current-carrying capability to serve as an adequate zero-voltage reference level.
Earthing has many benefits. Just as the sun gives us warmth and vitamin D, the Earth underfoot gives us food and water, a surface to walk, sit, stand, play, and build on, and something you never, ever thought aboutâan eternal, natural, and gentle energy. Think of it perhaps as vitamin GâG for ground. What does that mean to you? Maybe the difference between feeling good and not so good, of having little or a lot of energy, or sleeping well or not so well.
