Line/load reactors are generally serial-connected to the input terminal of three phase systems such as motor speed controllers which operate under IGBT method.
These reactors are designed in order to provide 4% voltage drop. Different voltage drop values are provided on demand.
Reactors reduce the harmonic current dissipated by the motor speed controllers, reduce the starting current, provide silent operation for motors, limit peak current, enable fuse selection depending on nominal motor current, decreases motor temperature, reduce over voltage (dv/dt) during switch off.
