2 and 3 Point Ground Resistance Meters from Megger

POSTED BY Protec Tech Team

With 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.
