Nettet23. feb. 2024 · Corona Effect in Overhead Transmission Line. The phenomenon of violet glow, hissing sound and production of ozone gas in an overhead transmission line is known as corona. When a very high voltage is applied across two conductors of the overhead transmission line whose spacing is large as compared to their diameters. In physics and electrical engineering, a conductor is an object or type of material that allows the flow of charge (electric current) in one or more directions. Materials made of metal are common electrical conductors. Electric current is generated by the flow of negatively charged electrons, positively … Se mer The resistance of a given conductor depends on the material it is made of, and on its dimensions. For a given material, the resistance is inversely proportional to the cross-sectional area. For example, a thick copper Se mer Conduction materials include metals, electrolytes, superconductors, semiconductors, plasmas and some nonmetallic … Se mer The ampacity of a conductor, that is, the amount of current it can carry, is related to its electrical resistance: a lower-resistance conductor can carry a larger value of current.
