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: Systems and methods for contact erosion mitigation are provided. To perform contact erosion mitigation, an order of opening/closing poles and/or contact relays of particular poles is altered, resulting in a sharing of potential arcing conditions amongst the poles/contact relays of these poles.

Abstract: A control system may include a processor that may receive a first dataset associated with a type of load device coupled to a relay device. The processor may then receive a second dataset associated with one or more operations of the load device over a period of time. The processor may also determine a switching profile to control moving an armature of the relay device between a first position and a second position based on the first dataset and the second dataset, such that the switching profile comprises a firing angle for moving the armature with respect to an electrical waveform. The processor may then control a current provided to a relay coil of the relay device based on the switching profile.

Abstract: A method may include receiving, via one or more processors, back electromotive force (EMF) data associated with each motor electrically coupled to a printed circuit board and determining, via the processors, a corresponding motor controller associated with each motor based on the EMF data. The motor controllers may be electrically coupled to the printed circuit board. The method may also include automatically adjusting, via the processors, circuit connections associated with the printed circuit board to route wiring that controls each motor to the corresponding motor controller.

Abstract: A method may include receiving, via at least one processor, a first set of data indicative of a fault being present and send a first signal to a breaker based on the first set of data. The first signal may cause the breaker to open a plurality of poles of the breaker. The method may then involve receiving a second set of data indicative of the fault being cleared and sending a second signal to the breaker based on the second set of data. The second signal may cause the breaker to close a first pole of the plurality of poles at a first time and close a second pole of the plurality of poles at a second time different from the first time.

Abstract: This disclosure describes a hybrid circuit breaker for an industrial automation system including a mechanical switch and solid-state switching circuit. The hybrid circuit breaker may receive control signals to open and close a current path based on moving a spanner of the mechanical switch. In some cases, moving the spanner of the mechanical switch may generate electrical arcs when the hybrid circuit breaker is conducting electrical current. In such cases, the hybrid circuit breaker may remove the electrical arcs based on operations of the solid-state switching circuit. The solid-state switching circuit may draw arc currents of the electrical arcs by providing a second current path between the spanner and a fixed conductor of the mechanical switch. Moreover, the solid-state switching circuit may open the second current path and absorb electrical power of the electrical arc by one or more solid-state switches, a parallel voltage suppressor, or both.

Abstract: A method includes receiving a first set of operational parameters that correspond to one or more semiconductor devices of a solid-state circuit breaker and sending a first command to the solid-state circuit breaker to turn off the one or more semiconductors in response to the first set of operational parameters exceeding a first set of thresholds. The method includes sending a second command to the solid-state circuit breaker to turn on the one or more semiconductors in response to the first set of operational parameters being equal to or less than the first set of thresholds. The method includes receiving a second set of operational parameters that correspond to one or more electrical properties associated with an operation of the solid-state circuit breaker coupled to a load device and generating a baseline profile representative of the first set of operational parameters and the second operational parameters.
