Electrical Ground Resistance Tester

Powered by 120 vac the tester applies direct current across the test specimen.

Electrical ground resistance tester.

Procedure details are given in the instruction manual. A clamp on ground meter is a specialized electronic machine that checks electrical resistance. 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.

There are two 2 methods for testing an electrical grounding system. 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. The standard used as a reference for fall of potential testing is ieee standard 81.

All components store in the tester s integral carrying case. Earth ground resistance tester meters two three wire digital earth resistance tester 2000ohm for electrical equipment rechargeable lithium battery ground resistance measurement by vtsyiqi 470 00 470. Discover our offering of earth ground resistance testers to help prevent electric shocks in your facility. However the video with travis christensen was misleading.

Guide for measuring earth resistivity ground impedance and earth surface potentials of a grounding system. Used for measuring resistance to earth of an installed grounding electrode. Use our digital ground testers to diagnose those electrical grounding problems and avoid electrical hazards improve system performance and reduce risks to costly equipment. These meters can range from about 100 usd to over 1500 for professional models.

They are available at hardware stores home improvement stores and online retailers of electrical supplies. Transcat offers ground testers from leading providers such as fluke megger hioki aemc that ensure every ground system application is properly covered. The measurement of ground resistance for an earth electrode system is very important. This was a good article.

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. The three point method is the most thorough and reliable test method. These testers are the key tools in ground electrode tests which are mandatory every three years according to the international electrical testing association. This tester provides an easy way for an electric utility to check the resistance in protective grounding sets used by line personnel.

It should be done when the electrode is first installed and then at periodic intervals thereafter.
