Current limiting reactor : ウィキペディア英語版 | Current limiting reactor In electrical engineering, current limiting reactors can reduce short-circuit currents, which result from plant expansions and power source additions, to levels that can be adequately handled by existing distribution equipment. They can also be used in high voltage electric power transmission grids for a similar purpose. In the control of electric motors, current limiting reactors can be used to restrict starting current or as part of a speed control system. == History ==
Current limiting reactors, once called current limiting reactance coils, were first presented at a Meeting of the Society of Mechanical, Electrical, and Steam Engineers, Boody House, Toledo, Ohio, in 1915. The inventor of the current limiting reactance coil was Vern E. Alden who filed the patent on November 20, 1917 with an issue date of September 11, 1923. The original assignee was Westinghouse Electric & Manufacturing Company.
