Abstract: Systems and methods for load management for electric grids. An example load management system includes a load management server associated with a utility and a first revenue meter communicatively connected to the load management server. The first revenue meter includes a first controller configured to determine a user priority of load distribution to a plurality of devices in communication with the first revenue meter and determine a current power drawn by the plurality of devices. The first controller is configured to transmit, in response to a load shed event and based on the user priority, a load shed command to the plurality of devices indicating a new amount of power to be drawn by the plurality of devices, and transmit an indication of the load shed event to the load management server.

Abstract: An electrical grid system including a phase conductor, a neutral conductor, and a neutral-to-ground conductor configured to conduct current flow between the neutral conductor and a ground. The electrical grid system further includes a fault detection sensor including a current sensor configured to sense current flowing along the neutral-to-ground conductor. The fault detection sensor further includes a controller having an electronic processor that is configured to receive signals indicative of the current flowing through the neutral-to-ground conductor from the current sensor, monitor the received signals for an occurrence of an event associated with the current flowing along the neutral-to-ground conductor; and output an occurrence of a fault in the electrical grid system based on detecting occurrence of the event.

Abstract: An energy harvesting device (CTH) installed in an electrical distribution system (EDS) for powering ancillary electrical devices (AD) used in the distribution system. The device includes a first voltage regulator circuit (CC) configured to produce a voltage matched to a power curve of a current transformer (CT) to which the device is electrically coupled. The device also includes a second and separate voltage regulator circuit (SVR) which continuously operates to maximize the amount of electrical energy recovered from the current transformer.

Abstract: An electric utility distribution system in which power is supplied by a distribution transformer through an electric utility meter including an apparatus for detecting the presence of a back-feed voltage source connected to the load. The apparatus includes a virtual neutral established in the electric utility meter at ground potential and a remote switch that is opened to interrupt electric power flow from the distribution transformer to the load. The apparatus further includes a balanced voltage divider circuit including a connection point established between a pair of series connected resistive elements. In addition, the apparatus includes a detection circuit configured to monitor a voltage signal at the connection point to detect a back-feed voltage source connected between a neutral conductor of the electric utility distribution system and one of a first or second power line at the load.

Abstract: A metering system including a utility meter having a processing circuit and a communication module interface. The metering system also includes a communication module electronically coupled to the utility meter via the communication module interface. The communication module interface is configured to transmit information to, and receive information from, the utility meter. The processing circuit of the utility meter includes one or more electronic processors that are configured to receive a first message from the communication, read a header frame of the first message, and determine a message type of the first message based on the header frame. The electronic processors are also configured to verify the first message based on the determined message type, and process the first message based on the determined message type.

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 sensor unit includes an orientation sensor, an electronic processor coupled to the orientation sensor, and memory coupled to the electronic processor and storing support structure configuration data and instructions. The instructions, when executed by the electronic processor, cause the sensor unit to monitor a position of a conductor support structure associated with the sensor unit based on data from the orientation sensor and generate an alert message responsive to determining that the position violates a position threshold. The position threshold is generated based on the support structure configuration data.
