Abstract: A method and system are provided for facilitating arc fault detection on an electrical system. In the method and system, a first device can measure or obtain measurements of high frequency signals, on a circuit monitored by a first sensor on the electrical system, which are used to determine high frequency features. A branch device(s) can measure or obtain measurements of low frequency signals, on an associated branch circuit(s) monitored by a second sensor(s), which are used to determine low frequency features on the branch circuit(s). The branch circuit(s) monitored by a second sensor(s) is downstream from the circuit monitored by the first sensor. The high frequency features and the low frequency are used by either the first device or the branch device(s) to detect for an occurrence of an arc fault on the branch circuit(s).

Abstract: A method, apparatus and computer program product resolve the problem of unbalanced loads in an EVSE cluster of multiple EVSE charging stations. A signal is provided to the EVSEs identifying which phase of the three-phase power source has the highest current. When one of the EVSEs in the cluster determines whether it is connected to an EV's on board charging device, determines whether it is already charging the connected EV, and determines whether the EVSE is using the phase that has the highest current, then the EVSE may transmit a cluster load balancing control signal as a control pilot signal to the EV's onboard charging device to adjust the charging rate of the current that the EV is consuming from the EVSE.

Abstract: Provided is a system and method to automatically identify metering constraints of one or more IEDs in an electrical system, which include capturing at least one energy-related waveform using at least one of the IEDs in the electrical system, and processing electrical measurement data from, or derived from, the at least one energy-related waveform to identify anomalous characteristics in the electrical system. In response to identifying anomalous characteristics in the electrical measurement data, an event constraint model is built based on or by using the identified anomalous characteristics. Once built, the event constraint model is analyzed to determine if the at least one energy-related waveform is being adequately captured by the at least one of the IEDs. In response to determining the at least one energy-related waveform is not adequately captured, one or more actions may be taken to address the capturing inadequacy.

Abstract: A circuit breaker with an integrated motorized racking mechanism, automatically provides electrical power to the racking motor when the breaker is inserted into a breaker compartment. The racking motor remains powered when the breaker is in either a disconnected position, a testing position, or a fully connected position. A racking power plug mounted within the circuit breaker conducts electrical power to the racking motor by automatically connecting to a stationary racking power receptacle mounted in the breaker compartment, and remains connected as the circuit breaker moves through the breaker compartment during the racking operation. A control power plug is mounted in the circuit breaker to connect to a stationary control power receptacle mounted in the breaker compartment and to conduct control power to control circuits in the circuit breaker after the racking motor has completed racking the circuit breaker into the connected position in the breaker compartment.

Abstract: A remote controlled miniature circuit breaker includes a helical gear that engages with mating teeth of a slider plate coupled to main contacts of the circuit breaker, the helical gear including a flat portion to allow the sliding plate to slide past the helical gear. A unidirectional motor responds to an external signal to drive the helical gear while engaging the mating teeth of the slider plate, thereby moving the slider plate to close the main contacts. The motor is configured to respond to an external signal to resume the unidirectional rotation of the helical gear to position the flat portion of the gear to allow the slider plate to slide past the helical gear and contact a kicker lever to thereby open the main contacts. A trip lever pivotally mounted separately from the kicker lever, pushes the kicker lever to open the main contacts in a trip operation.

Abstract: Embodiments provide techniques for securely managing the transmission of register operations to endpoint devices (e.g., circuit breakers and other forms of electrical equipment). A firewall management component can add, through a secure communications channel, an entry to a firewall structure maintained on a firewall device. The entry can specify (i) a register operation for an endpoint device, (ii) a value for the register operation, and (iii) a count of times that the register operation can be performed. The firewall management component transmits register operation to the firewall device to be forwarded to the endpoint device. The firewall device is configured to forward the register operation to the endpoint device only if the count specified in the firewall structure would not be exceeded.

Abstract: A draw out circuit breaker has a reduced partial discharge in insulation surrounding a primary stab bus. A circular disk plate on one end of the bus includes tapped inserts located at a radial separation distance from the bus. An insulator sleeve surrounding the bus is formed to encapsulate the tapped inserts. Raised embosses on the circular disk plate separate the end portion of the insulator sleeve by a gap distance from the inward facing surface of the disk plate. The increased gap distance reduces formation of a triple point region between the surface of the disk plate and the insulator sleeve, thereby reducing occurrence of partial discharges in the insulator sleeve near the gap.
