Clamp-on earth resistance tester It is a tool or tester used to save time effectively. It works on the principle of Ohms law. Here the user does not have to have to disconnect the ground system to process measurement. The clamp has the following parts connected with it: A transmitter coil, which implements the voltage, and Receiver coil, which measures the current
Clamp earth resistance tester can measure the connection resistance of any looped system without using an auxiliary ground rod or interrupting the grounding of the equipment under test. As long as the ground wire or ground rod is clamped with the clamp head, the ground resistance can be measured safely and quickly. It can also be applied to multiple parallel grounding systems.
