EARTHING SYSTEM

 

An earthing system (UK and IEC) or grounding system (US) connects specific parts of an electric power system with the ground

An earthing system (UK and IEC) or grounding system (US) connects specific parts of an electric power system with the ground, typically the Earth's conductive surface, for safety and functional purposes. The choice of earthing system can affect the safety and electromagnetic compatibility of the installation. Regulations for earthing systems vary considerably among countries, though most follow the recommendations of the International Electrotechnical Commission. Regulations may identify special cases for earthing in mines, inpatient care areas, or in hazardous areas of industrial plants.
