The Megger DET Line of Ground Resistance Meters

Posted by Protec Tech Team on

A ground is a crucial component in any electrical system. It routes electricity to the Earth when electrical insulation fails. Ultimately, it provides a definitive path in theses instances and prevents the electrical path from including anyone or anything else. Additionally, enclosures for electrical apparatus as well as radial conductors for cabling are often grounded in order to provide shielding from electrical noise or radiated interference.

Technicians perform Earth resistance testing to ensure ground rods and/or grounding systems  are well bonded and provide a low resistance path to ground. The resistance of the grounding system to the Earth may be affected by factors like the resistivity of the soil itself, damaged or partially uprooted stake, as well as corroded connections and broken ground leads. 

One of the fastest and most convenient methods of measuring ground resistance is by using the clamp method. Instead of using multiple leads or poles, the device has a jaw that can be clamped around the ground rod. The device then gives you the resistance reading in a few seconds. This method saves you from a lot of time and makes diagnostics faster.

megger_det24c-4To help you on ground resistance measurement, you might want to check out meters from Megger Test Equipment. The Megger DET24C Ground Resistance Tester is a clamp-on device that has a smooth jaw design and a large diameter that can accept grounding rods or cables with a diameter of 37 millimeters. Another great feature of this device is its built-in EMI suppression circuitry. This feature lets you accurately measure ground resistance even in environments with a high amount of electrical noise.
