Abstract: A system includes an electrical enclosure, an industrial automation component disposed within the electrical enclosure, in which the industrial automation component is configured to receive external power from an external power source to perform an operation, a display configured to maintain presentation of image data in absence of the external power being received by the industrial automation component from the external power source, and a control system communicatively coupled to the industrial automation component and to the display. The control system is configured to perform operations that include receiving an indication that the external power is within a range of a threshold, in which the threshold is associated with an insufficient amount of power for the industrial automation component to operate, identifying an error associated with the industrial automation component in response to receiving the indication, and causing the display to render image data indicative of the error.

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: A relay device may include an armature that moves between a first position that electrically couples the armature to a first contact and a second position that electrically couples the armature to a second contact. The relay device may also include a relay coil that receives a voltage to magnetize the relay coil, thereby causing the armature to move from the first position to the second position. The relay device also includes an additional coil that couples in series with the relay coil via a switch. The relay device also includes a drive circuit that causes the switch to couple the additional coil to the relay coil in response to receiving a signal indicative of the relay coil energizing.

Abstract: A system includes a relay system and a controller. The relay system includes a plurality of relays. The controller is configured to transmit a close signal to a first relay and a second relay of the plurality of relays. The close signal is configured to close the first contact and the second contact of each of the first relay and the second relay. The controller is also configured to measure a first close time between the transmission of the close signal to the first relay and a time when the first relay closes, and to measure a second close time between the transmission of the close signal to the second relay and a time when the second relay closes. The controller is further configured to determine whether an electrical weld exists in the first relay or the second relay, based on the first and second close times.

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.

Abstract: A method may include receiving a command to move one or more armatures configured to move between a first position that electrically couples one or more first movable contacts to one or more second contacts and a second position that electrically uncouples the one or more first movable contacts from the one or more second contacts. The method may also include determining an operating frequency of the system, dynamically determining an open-before-zero target point associated with the operating frequency, and transmitting a command to the switching device to move the one or more armatures from the first position to the second position at the open-before-zero target point to normalize the arc energy over the operating frequency range.

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.
