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. 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: A non-transitory, computer-readable medium may include instructions executable by at least one processor in a computing device to cause the processor to perform operations that include transmitting, to a first power source, a command to provide power to a coil of a switching device with a fixed current profile. The operations also include receiving one or more voltage measurements associated with the coil during a period of time, determining whether the voltage measurements associated with the coil indicate that one or more movable contacts of the switching device are at least partially welded to one or more contacts of an electric circuit, and transmitting an additional command to a second power source to disconnect a current to the coil in response to determining that the voltage measurements indicate that the movable contacts of the switching device are at least partially welded to the contacts of the electric circuit.

Abstract: A system includes a relay system and a controller. The relay system includes a plurality of relays, each having a first contact on an input side of the respective relay, the input side coupled to a power source, a second contact on a load side of the respective relay coupled to a load, and a spanner configured to close the first and second contacts of the respective relay when activated by a close signal. The load sides of each of the respective relays are coupled through their respective loads. The controller is configured to measure a voltage between a spanner of a first relay and an input side of a second relay. Based on the voltage between the spanner of the first relay and the input side of the second relay, the controller determines whether an electrical weld of one of the contacts of the first relay exists.

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 system may include a relay device that includes armatures associated with phases of voltage signals. The system may also include relay coils, such that each relay coil may receive a respective voltage that magnetizes a respective relay coil, thereby causing the respective armature to move from a respective first position to a respective second position. The system may also include a control system that receive an indication that a fault condition is present, identify a first phase of the phases of voltage signals that is expected to be the next phase of the phases to cross zero, and send a signal to the relay device in response to identifying the first phase. The signal is configured to cause a first relay coil of the relay coils to energize or deenergize.

Abstract: A system may include a relay device. The relay device may include an armature that moves between a first position that electrically couples a first contact to a second contact and a second position that electrically uncouples the first contact from the second contact. The relay device may also include a relay coil that receives a voltage configured to magnetize a relay coil, thereby causing the armature to move from the first position to the second position. The system also includes a control system that receives an indication that the armature is in the second position and sends a signal to an actuator in response to receiving the indication. The signal causes an arm associated with the actuator to move the armature to achieve a gap distance between the first contact and the second contact.

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.
