Electrical ground resistance tester.

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. Discover our offering of earth ground resistance testers to help prevent electric shocks in your facility. Transcat offers ground testers from leading providers such as fluke megger hioki aemc that ensure every ground system application is properly covered. The three point method is the most thorough and reliable test method.

Powered by 120 vac the tester applies direct current across the test specimen. The standard used as a reference for fall of potential testing is ieee standard 81. Used for measuring resistance to earth of an installed grounding electrode. The goal in ground resistance testing is to achieve the lowest ground resistance value possible.

The measurement of ground resistance for an earth electrode system is very important. This tester provides an easy way for an electric utility to check the resistance in protective grounding sets used by line personnel. Use our digital ground testers to diagnose those electrical grounding problems and avoid electrical hazards improve system performance and reduce risks to costly equipment. When he measured the resistance of the ground rods he measured above the electrical connection.

This ensures that the resistance to ground does not increase over time. Browse our top selling 1623 2 geo earth ground resistance meter 1625 2 geo earth ground tester and the 1630 ground resistance meter today. However the video with travis christensen was misleading. These meters can range from about 100 usd to over 1500 for professional models.

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. All components store in the tester s integral carrying case. There are two 2 methods for testing an electrical grounding system. I noticed that the camera did not show the reading on the meter when it was placed like this.

A clamp on ground meter is a specialized electronic machine that checks electrical resistance. These testers are the key tools in ground electrode tests which are mandatory every three years according to the international electrical testing association. Procedure details are given in the instruction manual. The ground rod tester will not work like this.

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.
