Abstract: Identifying proper regulation method based on average voltage change between tap steps for voltage regulators. In response to a first tap step index being different from a second tap step index of a preceding tap operation, an electronic processor determines whether an average of a first voltage change of the current tap operation and a second voltage change of the preceding tap operation satisfies a voltage threshold. The electronic processor is configured to change a regulation direction of the voltage regulator when the average satisfies the voltage threshold and maintain the regulation direction of the voltage regulator when the average does not satisfy the voltage threshold. The electronic processor is configured to provide regulation settings to the voltage regulator corresponding to a current regulation mode and regulation direction of the voltage regulator.

Abstract: A circuit interrupting device including a vacuum interrupter, a separable ceramic capacitor, and an insulating housing. The vacuum interrupter includes a vacuum bottle and first and second contacts disposed within the vacuum bottle. The second contact is movable relative to the first contact between a closed position and an open position. The separable ceramic capacitor is electrically connected in parallel with the vacuum interrupter provided over an outer surface of the vacuum bottle. The insulating housing encloses the separable ceramic capacitor and the vacuum interrupter.

Abstract: An electrical conduit body assembly is provided. The assembly includes a body portion, a cover, and a movable connection. The movable connection connects the body portion and the cover to one another so that the cover can be moved with respect to the body portion between an open state and a closed state in a manner that prevents the cover from being misplaced or disassociated from the body portion.

Abstract: Devices, systems and methods are provided to improve communication of switch sensor and status signals between a medium voltage overheard switchgear and an intelligent electronic device (IED). A switchgear interface device is deployed proximally to a switchgear and/or junction box situated at a distal end of a utility pole. The switchgear interface device (SID) receives, processes and combines sensor signals and status signals from switches in the switchgear with metadata for transport as digital signals to an IED mounted at the other end of the utility pole. The cabling for sensor and status signals between the SID and the IED can be fiber or Ethernet. The digital signals can be formatted using the IEC61850 standard. The SID can have drive electronics and send open and close command signals to the switches to eliminate the need for a multi-pin connector cable for transport of switch power signals from the IED.

Abstract: An antenna tray system includes a first tray for being disposed in a recess in a floor; a second tray disposed in the first tray; and an antenna PCB disposed in the second tray, the antenna PCB including antenna leads extending through the first and second trays and the floor for connection to an access point.

Abstract: Underground utility enclosure cover assemblies for use with direct burial enclosures. The cover assemblies include a frame and a cover. The frame has one or more walls that define a central opening, a cover receiving ledge, an overhang that has a side wall, and at least one stabilizing member extending from the bottom edge of the sidewall of the overhang. The cover is dimensioned to rest on the cover receiving ledge. The frame and the cover are made of a rigid material that permits the frame and cover to support large vertical test loads.
