    Abstract: The present technology relates to circuit breaker devices having current sense transformers. The current sense transformer includes a core, a secondary winding, and a primary winding coupled to the power input. The secondary winding includes a first wire wrapped around the core a number of secondary winding turns. The primary winding includes a second wire wrapped around the core a number of primary winding turns. The number of primary winding turns includes a first number of primary winding turns in a first direction and a second number of primary winding turns in an opposite direction that magnetically cancel out the second number of primary winding turns in the first direction to generate an effective number of primary winding turns. The effective number of primary winding turns and the number of secondary winding turns make up a desired turns ratio.

    Abstract: This disclosure describes a hybrid circuit breaker for an industrial automation system. The hybrid circuit breaker may include a mechanical switch and solid-state switches. 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 by drawing the electrical arcs to a conductive bar and away from the spanner. Moreover, the hybrid circuit breaker may dissipate the electrical arcs on the conductive bar by opening one or multiple solid-state switches disposed on the conductive bar. In some cases, one or multiple voltage suppressors may receive (e.g., suppress or ground) an electrical power of the electrical arcs when the solid-state switches are opened.

    Abstract: This disclosure describes a hybrid circuit breaker for an industrial automation system. The hybrid circuit breaker may include a breaker switch and a solid-state switching circuit coupled in parallel. Moreover, the hybrid circuit breaker may include a disconnector switch coupled in series with the breaker switch. For example, the solid-state switching circuit may include a number of solid-state devices. A control system may provide control signals to the disconnector switch, the breaker switch, and the solid-state switching circuit to switch on and switch off the hybrid circuit breaker. The hybrid circuit breaker may enable or reduce (e.g., halt) electrical current flow based on receiving the control signals. Operation of the breaker circuit and the solid-state switching circuit that are coupled in parallel may provide reduced heat generation while providing safe switching of the hybrid circuit breaker. Moreover, operation of the disconnector switch may provide galvanic isolation.

    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: 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.
