jordpunkt

Jordpunkt is a term used in Scandinavian languages to denote a reference point related to the earth or ground. The word combines jord, meaning earth or ground, with punkt, meaning point. It is employed in several disciplines, most notably electrical engineering and geodesy, as well as in everyday technical language.

In electrical engineering, jordpunkt refers to the grounding point that establishes a zero-potential reference for a circuit and provides a path for fault currents to earth for safety. This point is typically connected to a grounding electrode system and to protective earth conductors. Standards and configurations vary by country, but the concept centers on creating a defined, low-impedance connection to the earth to reduce the risk of electric shock and equipment damage. The jordpunkt is distinct from, though sometimes bonded to, the neutral point in power systems, depending on local regulations.

In surveying and geodesy, jordpunkt can describe a physically marked reference point on the Earth's surface used to anchor coordinate systems, control networks, or maps. Such benchmarks serve as stable origins from which measurements are taken and coordinates are referenced.

In education and technical usage, jordpunkt is often translated as ground or earth, depending on the context. In electronics, it corresponds to the zero-voltage node, while in mapping and surveying it denotes a ground-based reference monument.
