Abstract: A node in a power distribution system is described. The node includes an electrical connection to a single-phase power signal from an AC mains power source, a wireless communication interface configured to receive a first phase synchronization message, and a controller. The controller is configured to determine whether the first phase synchronization message is acceptable and detect a zero-crossing event on the single phase power signal subsequent to the receipt of the first phase synchronization message in response to determining that the first phase synchronization message is acceptable. The controller is further configured to calculate a time difference between the receipt of the first phase synchronization signal and the detected zero-crossing event, determine a local phase angle based on the time difference, and establish an identity of the single phase power signal based on the local phase angle.

Abstract: Systems and methods for monitoring and/or protecting state-of-charge of one or more batteries. One method comprises determining, via a controller, location information associated with the battery. The method includes determining, via the controller, one or more battery parameters. The method includes calculating, based on the one or more battery parameters and the location information, a state of charge of the battery. The method includes controlling, via the controller and based on the state of charge, a mode of the battery.

Abstract: A light dimming system includes one or more lights and includes a local light controller that includes a dimming controller and a processing circuit, the dimming controller configured to provide an output to the one or more light drivers. One or more electronic processors are configured to receive a dimming input value indicating a desired dimming level for the one or more lights. The processors are further configured to determine a configuration of the one or more light drivers, wherein the configuration defines whether the one or more light drivers utilize a non-linear dimming curve or a linear dimming curve, and provides the dimming controller a dimming level to output a dimming control signal to the one or more light drivers equivalent to the received dimming input value based on a non-linear or linear calculation.

Abstract: A switched capacitor bank assembly including a first capacitor, a first switch selectively connected between the first capacitor and a first phase line, and a first voltage sensor integrated within a housing of the first switch and configured to sense a voltage of the first phase line. The assembly further includes a controller including an electronic processor, the controller operably coupled to the first voltage sensor and the first switch. The first capacitor, the first switch, the first voltage sensor, and the controller are physically supported by a frame of the switched capacitor bank assembly.

Abstract: A contaminant detector is capable of sending a signal or alert when a contaminant is detected within a housing of a utility meter, a meter transmission unit (MTU), or other associated equipment. Circuitry enclosed within the housing is capable of detecting utility usage, transmitting information between one or more utility meters and a utility provider, and/or otherwise monitoring or tracking utility usage. The contaminant detector includes a resistive voltage divider network having a resistance that varies when in contact with a contaminant such as a form of water or metal. The variable resistor has a serpentine structure comprising a plurality of detective fingers that are formed from conductive material and separated by a non-conductive substance.

Abstract: A utility device within a utility system and including a power source, a communication interface, and one or more electronic processors. The processors are configured to periodically transition from a standby mode into a receive mode and monitor for a broadcast message while in the receive mode. The electronic processors are also configured to receive a broadcast message via the communication module while in the receive mode and analyze a header of the received broadcast message to determine whether the received broadcast message is relevant. The broadcast message is determined to be relevant based on the received broadcast message including one or more data packets associated with a unique network ID of the utility device as defined in the header. The electronic processors are also configured to resume operation in the standby mode in response to determining that the received broadcast message is not relevant.
