Abstract: A control system may include a processor that may receive a first dataset associated with a current received at a load device coupled to a relay device. The processor may also determine harmonics data associated with the current and determine a switching profile to control moving a first armature of three armatures in the relay device based on the harmonics data. The switching profile is configured to control movement of the first armature between a first position and a second position, and wherein the switching profile comprises a firing angle for moving the first armature with respect to an electrical waveform, a second armature, and a third armature. The processor may then control a current provided to a relay coil of the relay device based on the switching profile, such that the relay coil causes the first armature to move.

Abstract: A control system may include a processor that may receive a first dataset associated with power properties of a rotating load device coupled to a relay device. The processor may also determine frequency properties based on the power properties and determine a switching profile to control moving a first armature of three armatures in the relay device based on the frequency properties. The switching profile is configured to control movement of the first armature between a first position and a second position, and wherein the switching profile comprises a firing angle for moving the first armature with respect to an electrical waveform, a second armature, and a third armature. The processor may then control a current provided to a relay coil of the relay device based on the switching profile, such that the relay coil causes the first armature to move.

Abstract: One embodiment describes a three-phase electromechanical switching device, which includes three single-phase switching devices mechanically and electrically coupled in parallel with one another. Each of the single-phase switching devices includes a direct current electromagnetic operator that receives a direct current control signal from control circuitry, in which the direct current control signal instructs the single phase switching device to open or close a single current carrying path in the single phase switching device at a desired time; stationary contacts disposed in a device housing; and a movable assembly that is displaced by energizing or de-energizing the electromagnetic operator, in which the movable assembly includes movable contacts that, with the stationary contacts, open and close the single current carrying path.
