The importance of ground potential in the earthing system Life protection: When an electrical device breaks down and its body is electrified, if it is connected to the ground, the excess electricity will go from

Current leakage in the earthing system is the passage of unwanted electric current through the ground, which can cause many dangers. Causes of current leakage in the earthing system: Faulty or frayed wiring: Damaged or frayed wiring can cause current leakage. Improper connections: Improper connections between wires can also lead to current leakage. Moisture: Moisture can reduce insulation resistance and leakage current. Overloading: Overloading the circuit can cause the wires to overheat and leak current. Faulty equipment: Faulty electrical equipment
