Damping the motor current peaks

1  Direct-on-line starting

2  Star-delta starting

3  Soft starting

Power supply companies are increasingly demanding adherence to certain current limits.

The aim is to avoid overloading the network due to high inrush currents during direct-on-line starting or current peaks during star-delta starting, in order to prevent unpleasant side effects such as voltage dips. Since the current limit can be set on softstarters, these provide the ideal solution.
