Jordningsmätare
Jordningsmätare, also known as earth testers or ground resistance meters, are instruments used to measure the resistance of an electrical ground connection. This resistance is a critical factor in ensuring electrical safety and the proper functioning of electrical systems. A low ground resistance is essential to safely conduct fault currents away from equipment and personnel, preventing electric shock and damage.
These devices typically operate by injecting a small current into the earth electrode and measuring the resulting
Jordningsmätare are indispensable tools for electricians, maintenance technicians, and safety inspectors. They are used during the
