A ground resistance tester, also known as an earth ground tester, is an instrument designed to measure the electrical resistance of the grounding system in various applications. Its primary function is to ensure that grounding systems are effective in safely dissipating electrical faults and preventing electrical hazards.
Ground resistance testers measure the electrical resistance of the ground electrode, grounding conductors, and the soil they are connected to. They work by injecting a known current into the ground and measuring the resulting voltage drop to calculate resistance.
An earth ground is used as a zero-volt reference point for power substations, buildings, communication towers, and as a path to dissipate lightning strikes to prevent damage to them.
Ground resistance is typically measured in ohms (Ω). The goal is to achieve low resistance values to ensure efficient dissipation of electrical currents into the ground. The NEC (National Electrical Code) requires that a single path to ground should be 25 ohms or less. If it is higher than 25 ohms, you should add an additional ground rod 6 feet away. The earth ground resistance tester provides an easy way to check this reading in installed systems or for a good location to install a new system.
