Electrical Ground Resistance Tester

The standard used as a reference for fall of potential testing is ieee standard 81.

Electrical ground resistance tester.

Browse our top selling 1623 2 geo earth ground resistance meter 1625 2 geo earth ground tester and the 1630 ground resistance meter today. Procedure details are given in the instruction manual. The ground rod tester will not work like this. I noticed that the camera did not show the reading on the meter when it was placed like this.

This ensures that the resistance to ground does not increase over time. There are two 2 methods for testing an electrical grounding system. They are available at hardware stores home improvement stores and online retailers of electrical supplies. Discover our offering of earth ground resistance testers to help prevent electric shocks in your facility.

Built to withstand an entire spectrum of ground testing methods fluke s family of earth ground testers have been designed to be accurate safe and easy to use. When he measured the resistance of the ground rods he measured above the electrical connection. All components store in the tester s integral carrying case. The measurement of ground resistance for an earth electrode system is very important.

Used for measuring resistance to earth of an installed grounding electrode. The most widely used specification for grounding is found in the national electric code which specifies residential grounds have a resistance of 25 ohms or less. Use our digital ground testers to diagnose those electrical grounding problems and avoid electrical hazards improve system performance and reduce risks to costly equipment. However the video with travis christensen was misleading.

It should be done when the electrode is first installed and then at periodic intervals thereafter. This tester provides an easy way for an electric utility to check the resistance in protective grounding sets used by line personnel. The three point method is the most thorough and reliable test method. Guide for measuring earth resistivity ground impedance and earth surface potentials of a grounding system.

These testers are the key tools in ground electrode tests which are mandatory every three years according to the international electrical testing association. This was a good article. A clamp on ground meter is a specialized electronic machine that checks electrical resistance. Powered by 120 vac the tester applies direct current across the test specimen.

The goal in ground resistance testing is to achieve the lowest ground resistance value possible.
