Accurate and Fast Ground Resistance Measurements with AEMC’s Ground Testers

AEMC 3711 Clamp On Ground Resistance Test SetGood grounding systems and proper wiring can help reduce power quality issues and reduce the risk of premature failure of the electrical system. Regular testing of the ground and the connections should be an active part of your preventive maintenance strategy. One of the time-saving and effective methods of testing grounding systems is by using a hand held clamp-on tester. These testers are used on multi-grounded electrical systems without disconnecting the ground.

Clamp-on testing offers several advantages over the traditional fall-of-potential method. One is you do not need to disconnect the grounding rod from the electrical system. You also do not need auxiliary rods that need to be the driver to the earth. This saves you time and effort during diagnostics. Clamp-on testing also tests not only the grounding rod but also the overall connecting resistance.

If you are thinking of investing in a clamp-on ground resistance tester, consider tools from AEMC. Below are some of AEMC’s popular clamp-on testers. 

AEMC 3711 Clamp On Ground Resistance Test Set

The 3711 measures ground rod and grid resistance in any location with a current measure function. It has a high sensitivity input which allows you to measure leakage current circulating in ground loops or current flowing in the ground. Measuring leakage current provides additional data which is vital in grounding systems carrying a high level of electrical noise and harmonics.
