Abstract

A method may include receiving a command to move one or more armatures of a switching device from a first position that electrically couples a first contact to a second contact to a second position that electrically uncouples the first contact from the second contact. The method may also include selecting a current zero-crossing point along an electric waveform indicative of a change in current through the first contact and the second contact as a synchronization point, determining a predicted current zero-crossing point by adding a period measurement associated with a previously detected current zero-crossing point or a previously detected line-to-line crossing point in the electric waveform to the synchronization point, and transmitting a command to the switching device to move the armatures from the first position to the second position before or at the predicted current zero-crossing point.
