Mains chokes

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
