Electrical Ground Resistance Tester

The ground rod tester will not work like this.

Electrical ground resistance tester. When he measured the resistance of the ground rods he measured above the electrical connection. These testers are the key tools in ground electrode tests which are mandatory every three years according to the international electrical testing association. Used for measuring resistance to earth of an installed grounding electrode. However the video with travis christensen was misleading.

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 standard used as a reference for fall of potential testing is ieee standard 81. A clamp on ground meter is a specialized electronic machine that checks electrical resistance. Procedure details are given in the instruction manual.

It should be done when the electrode is first installed and then at periodic intervals thereafter. The goal in ground resistance testing is to achieve the lowest ground resistance value possible. This was a good article. 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. The three point method is the most thorough and reliable test method. There are two 2 methods for testing an electrical grounding system. Guide for measuring earth resistivity ground impedance and earth surface potentials of a grounding system.

Use our digital ground testers to diagnose those electrical grounding problems and avoid electrical hazards improve system performance and reduce risks to costly equipment. The measurement of ground resistance for an earth electrode system is very important. Discover our offering of earth ground resistance testers to help prevent electric shocks in your facility. I noticed that the camera did not show the reading on the meter when it was placed like this.

All components store in the tester s integral carrying case. This tester provides an easy way for an electric utility to check the resistance in protective grounding sets used by line personnel. This ensures that the resistance to ground does not increase over time. 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.
