WebThe NEC defines the term “grounding electrode” as “a conducting object through which a direct connection to earth is established.” The 2005 NEC first defined the term, and the definition has been subsequently revised … Web(Redirected from Ufer Ground) The Ufer ground is an electrical earth grounding method developed during World War II. It uses a concrete-encased electrode to improve grounding in dry areas. The technique is used in construction of concrete foundations. History [ edit]

In electrical engineering, ground or earth is a reference point in an electrical circuit from which voltages are measured, a common return path for electric current, or a direct physical connection to the Earth. Electrical circuits may be connected to ground for several reasons. Exposed conductive parts of electrical … See more Long-distance electromagnetic telegraph systems from 1820 onwards used two or more wires to carry the signal and return currents. It was discovered by German scientist Carl August Steinheil in 1836–1837, that … See more Signal grounds serve as return paths for signals and power (at extra-low voltages, less than about 50 V) within equipment, and on the signal interconnections between equipment. Many electronic designs feature a single return that acts as a reference for all … See more Lightning protection systems are designed to mitigate the effects of lightning through connection to extensive grounding systems that provide a large surface area connection to earth. … See more In an electrical substation a ground (earth) mat is a mesh of conductive material installed at places where a person would stand to operate a switch or other apparatus; it is … See more Electrical power distribution systems are often connected to earth ground to limit the voltage that can appear on distribution circuits. A … See more In single-wire earth return (SWER) AC electrical distribution systems, costs are saved by using just a single high voltage conductor for the power grid, while routing the AC return current through the earth. This system is mostly used in rural areas where large earth … See more Certain types of radio antennas (or their feedlines) require a connection to ground. Since the radio frequencies of the current in radio antennas are far higher than the 50/60 Hz frequency of the power line, radio grounding systems use different principles from AC … See more Webn. 1.
