Earth Resistance TestDefinition:An earth resistance test is a procedure carried out to measure the resistance of the earth electrode (earth rod, plate, or mat) to the general mass of the earth. The main goal is to ensure that fault current can safely flow into the ground without endangering people or equipment.Purpose of the Test 1. Safety of People – Ensures exposed metallic parts don’t remain live during a fault. 2. Protection of Equipment – Helps protective devices (fuses, RCCB, MCB) operate
