Current limiting reactors are now widely used to control fault currents in both utility and industrial power systems. The primary advantages of a current limiting reactor are: Reduction of electromechanical loading and thermal stress of transformers and switchgears. Improvement of the stability of primary bus voltage during a fault on feeder

04/08/2020· Proponents of molten salt reactors expect that electric power from MSR nuclear plants will actually be cheaper than electric power from coal-burning power plants. In other words, once the technology is proven on a commercial scale (by the project underway in China), it will be more economical to build MSR nuclear plants than to build new coal-burning power plants.

Current Limiting Reactors are connected in series with the power system essentially to damp the short circuit fault current. During normal operation, a continuous current flows through the reactor. Current limiting reactors are now widely used to control fault currents in both utility and industrial power systems.
