Triangle earthing system
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 among countries, though most follow the recommendations of the International Electrotechnical Commission (IEC). Regulations may identi… WebThis process of sharing the charges with the earth is called earthing. Earthing is a simple way for the leakage of current and hence protects the devices from electrical damage. Grounding is also a safety process that protects the entire power system from malfunctioning and is mainly used to balance the load when the electric system overloads.

Those ground bars are then tied to the grounding grid. This is often done with a triangular arrangement with three earth rods that are tied together via copper conductor. One rod is connected to the Instrument ground, one to safety ground etc.
WebThe entire earthing system of the building is set up around the earth electrode. The earthing system usually comprises the following elements: the earth conductor, the main earth terminal, the measurement bar, the protective conductor, the main equipotential bond and the local equipotential bond.
