Digital earth tester, also known as a grounding resistance tester or earth megger, is an instrument used to measure the resistance of the grounding or earthing system in electrical installations. It helps ensure electrical safety by verifying that the grounding system is functioning correctly and can safely dissipate fault currents.
Key Features and Functions:
Earth Resistance Measurement:
The primary function is to measure the resistance between an electrical device and the earth. This is crucial for ensuring that a fault current can be safely diverted to
