Starting Reactor
A Starting Reactor is a specialized type of reactor used in electrical power systems to limit inrush current during the startup of motors, transformers, or other heavy electrical equipment. The Starting Reactor protects equipment from overcurrent, reduces voltage dips, and ensures a smooth start-up process, making it an essential component in industrial and utility power networks.
Working Principle of Starting Reactor
The Starting Reactor is connected in series with the electrical load during startup. When the load is energized, the Starting Reactor provides inductive reactance, which limits the initial inrush current. By gradually reducing the current surge, the Starting Reactor prevents mechanical stress on motors, avoids tripping protection devices, and minimizes disturbances in the electrical network. Once the equipment reaches stable operating conditions, the Starting Reactor can be bypassed or removed from the circuit.
