Abstract: A circuit breaker includes two or more poles electrically connected between a power supply and a contactor. Each of the two or more poles comprises a switch. The circuit breaker includes one or more voltage measuring devices configured to measure at least one phase-to-phase voltage level, and one or more current detecting devices configured to detect current going through each of the two or more poles. The circuit breaker further includes a control circuitry configured to: monitor the at least one phase-to-phase voltage level; in response to determining the at least one phase-to-phase voltage level is within a threshold range, close corresponding switches; in response to detecting current flowing through at least one of the two or more poles, maintain the corresponding switches in a closed position; and close all additional switches associated with the two or more poles after a period of time.

Abstract: A method may include receiving a command to move one or more armatures of a switching device from a first position that electrically couples a first contact to a second contact to a second position that electrically uncouples the first contact from the second contact. The method may also include selecting a current zero-crossing point along an electric waveform indicative of a change in current through the first contact and the second contact as a synchronization point, determining a predicted current zero-crossing point by adding a period measurement associated with a previously detected current zero-crossing point or a previously detected line-to-line crossing point in the electric waveform to the synchronization point, and transmitting a command to the switching device to move the armatures from the first position to the second position before or at the predicted current zero-crossing point.

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 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 may include an armature configured to move 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 system may also include a coil configured receive a current, such that the current conducting in the coil is configured to magnetize a core. The magnetized core may cause the armature to move from the first position to the second position. The system may also include a control system configured to detect a position of the armature based on an inductance of the coil.
