Abstract: Various embodiments disclosed herein provide techniques for detecting electrical arcing in an electrical system. A powerline communications (PLC) application executing on a network communications device acquires, via a PLC modem, first voltage readings associated with an electrical circuit. The PLC application performs one or more operations based on the first voltage readings to determine that an electrical arcing condition is present within the electrical circuit. The PLC application performs a remedial operation in response to determining that the electrical arcing condition is present.

Abstract: Various embodiments disclosed herein provide techniques for detecting electrical arcing in an electrical system. The techniques include a network device receiving first voltage or current readings associated with a first power cycle, receiving second voltage or current readings associated with a second power cycle, determining that an electrical arcing condition is present by comparing the first voltage or current readings with the second voltage or current readings, and performing a remedial operation in response to determining that the electrical arcing condition is present.

Abstract: Techniques for computing electrical phase of electrical metering devices are described. In an example, data indicating zero-crossing times at first and second metering devices is obtained. A time-difference between the zero-crossing times may be determined. In a first example, the time-difference may be based at least in part on calculations involving a first value of a first free-run timer on a first metering device, a second value of a second free-run timer on a second metering device, and a time of a transmission between the metering devices. In a second example, the time-difference may be based at least in part on calculations involving a start or end time of a time-slot of a spread spectrum radio frequency transmission scheme. A phase difference between the first zero-crossing and the second zero-crossing may be determined, based at least in part on the determined time-difference.

Abstract: Techniques for detecting hot socket conditions in utility electricity meters include acquiring, by an electricity meter, first signal readings of one or more first signals associated with a first type of communications between the electricity meter and one or more first devices; acquiring, by the electricity meter, second signal readings for one or more second signals associated with a second type of communications between the electricity meter and one or more second devices, the second type of communications being different from the first type of communications; performing, by the electricity meter, one or more operations on the first signal readings and the second signal readings to determine whether a hot socket condition is present; and performing, by the electricity meter, a remedial operation in response to determining that the one or more operations indicate that the hot socket condition is present.

Abstract: A method includes computing electrical phase of electrical metering devices including obtaining data indicating zero-crossing times at first and second metering devices. A time difference between the zero-crossing times may be determined. In a first example, the time difference may be based at least in part on calculations involving a first value of a first free-run timer on a first metering device, a second value of a second free-run timer on a second metering device, the time of reception of a packet, and a latency defined by a time taken for the packet to propagate through at least one layer of at least one of the first metering device and the second metering device. A phase difference between the first zero-crossing and the second zero-crossing may be determined, based at least in part on the determined time difference.
