It is important to create an earth to protect people and electronic devices and equipment and sensitive industrial tools and equipment. The purpose of creating this system is that if any of the phase wires or neutral wire is connected to the body of the device in any way and the electrical circuit The desired leakage current; This current leakage is transmitted by ground wire to ground, which has zero potential, and is prevented from being electrocuted or in some cases connected to the device. The earthing system consists of an earth well and a wire connected to the well.
