Switching phase offset for contactor optimization

摘要

A system and methods providing for minimizing the arc energy delivered to the pads of a plurality of contactors using a single control coil based on monitoring the electrical sine waves of the three alternating current electrical poles and calculating the instant to energize or deenergize a single control coil. The remainder of the contactors will make or break based on an offset in time from the making or breaking of the control contactor.
