Inrush Limiting Reactors
Neutral earthing Reactors: The application of neutral earthing reactors is to increase the impedance in the neutral point of a transformer or a shunt reactor. During single phase faults the reactor limits the fault current in the neutral and the restoration of the power line is improved. The design can be dry-type or oil-immersed.
Shunt Reactor: The shunt reactor compensates the capacitive generation on power lines to avoid non-controlled voltage rise especially on lightly loaded lines. The simple design and robust build-up makes the shunt reactor the most cost efficient mean to compensate the capa capacitive generation.
Smoothing Reactor: The direct current that comes from the rectifier in the DC system has superimposed harmonic components, also called ripple. The smoothing reactor is connected in series with the rectifier and the whole load current flows through it. The purpose of the reactor is to provide high impedance to the flow of the harmonic currents, reduce their magnitude and thus making the DC current more smooth.
Inrush Limiting Reactor: Damping reactors limit the inrush and outrush currents of capacitor banks. Also used in series compensation systems in the bypass/discharge circuit to limit the capacitor discharge current.
Line/Load Reactor: 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.
