Earth conductor
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 ident… WebDisadvantages Here are some of the disadvantages of voltage ELCB It cannot sense the current leakage from phase to any other earthed body. It cannot prevent electrical shock in case of touching the phase conductor directly. It only trips when the leakage current flows through the earth conductor. It requires an extra connection between the body ...

Electrical power distribution systems are often connected to earth ground to limit the voltage that can appear on distribution circuits. A distribution system insulated from earth ground may attain a high potential due to transient voltages caused by static electricity or accidental contact with higher potential circuits. An earth ground connection of the system dissipates such potentials and limits the rise in voltage of the grounded system.
