Ground Resistance

The Megger DET Line of Ground Resistance Meters

A ground is a crucial component in any electrical system. It routes electricity to the Earth when electrical insulation fails. Ultimately, it provides a definitive path in theses instances and prevents the electrical path from including anyone or anything else. Additionally, enclosures for electrical apparatus as well as radial conductors for cabling are often grounded in order to provide shielding from electrical noise or radiated interference.

2 and 3 Point Ground Resistance Meters from Megger

Megger DET3TD Digital Ground TesterWith the advancement in ground resistance measurement technologies, much of the test equipment currently available for this purpose now provide the convenience of Clamp-On technologies that are in some applications preferable to the traditional 2-3 point testing methods. These clamp-on ground resistance meters provide the potential to save valuable time and effort by inducing a current into the ground through electromagnetic coupling. The jaws then sense the voltage drop around the loop and automatically calculate the ground resistance using Ohm’s Law.
