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.
Ground: means the physical earth, the soil or ground. In some countries the term earth is used and is synonymous with ground. In the electrical code, ground means an electrically conducting connection, intentional or accidental, between an electrical circuit and the earth.n an electrical circuit the grounded conductor (white or neutral wire) normally carries electrical current between the un-grounded (hot) electrical wire and (back through the main electrical panel and grounding system) earth.
