Earth & Ground Resistance Testers
Earth & Ground Resistance Testers
It is critical for facilities to have well grounded electrical systems, so that in the event of a lightning strike or utility overvoltage, current will find a safe path to earth. To ensure a reliable connection to earth, testing of the ground electrode and associated system must be carried out on a periodic basis
Earth resistance and resistivity measurements can be accomplished using several test methods: 3 and 4 pole fall of potential testing, selective measurement testing, stakeless testing and 2 pole testing.
