High voltage transmission lines kv

WebThe majority of major transmission lines in the U.S. are either 230-kilovolt ( kV) or 500-kV alternating current lines. In some cases, 115-kV lines are used. Lower voltages are far less efficient for moving electricity across hundreds or thousands of miles to where it is needed without losing a significant amount of energy. WebVery high voltage lines (345 kV) can carry high current and as a result produce relatively high magnetic fields. The size of the magnetic fields from electric distribution lines ... Power lines with voltages of 69 kV or more are generally considered transmission lines, not distribution lines. Service lines serve your home and provide the 240/ ...
