Mains chokes

Reduce noise and save money with mains chokes

A line reactor relieved the supply network by compensating the harmonics reactive power, The harmonics are greatly reduced .

The conditional by the operating principle of rectification very high current peak is attenuated by the inductance by more than 60 %.

 Why the additional installation of a line reactor ?

- Attenuation of the very high current peaks up to 40%

- Minimizing the deformation of the sinusoidal mains voltage

- Discharge of the supply system by reactive power compensation

- Limitation of mains disturbances like voltage sags and spikes

    Power Noise Reduction - save up to 20% energy costs.


    A mains choke relieved the supply network by compensating the harmonics reactive power. The harmonics and commutation notches are reduced strongly. By efficiently cooling the power losses is dissipated up to 80% in cooling and reduces heating of switching cabinets. The targeted derivative of the losses via the cooling circuit prevents that losses are discharged into the environment. By using water cooling the temperatures in the components can be reduced greatly - this means less stress for the insulation materials and a longer service life.
