jordningen
Jordningen, or grounding (earthing), is the practice of connecting an electrical installation to the earth to establish a common reference potential and provide a low-impedance path for fault currents. The primary purpose is safety: to limit touch voltages, enable protective devices to operate quickly, and reduce the risk of electric shock and fire.
In electrical systems, jordningen serves to route fault currents away from people and equipment. A stable earth
There are several system approaches, including TT, TN, and IT. In a TT system, the installation has
Key components include ground electrodes (rods, plates, or mats), main earth conductors, and bonding connections that
