Applications:
Digital earth resistance testers are essential for verifying the safety and integrity of grounding systems in electrical installations, power circuits, and telecommunication networks. They accurately measure earth resistance and soil resistivity, ensuring a reliable path for fault current to protect personnel and equipment from electrical hazards like lightning and voltage spikes.


Measuring Principle:
Digital earth resistance testers primarily use the Fall-of-Potential method to measure ground resistance: they inject a known AC current (I) into the earth via an auxiliary spike and measure the resulting voltage drop (V) across a second spike, then automatically calculate the resistance (R = V/I) based on Ohm's Law.
