Abstract: In one embodiment, a multi-function energy meter apparatus is described. The multi-function energy meter apparatus includes (a) measurement circuitry configured to measure one or more energy-related parameters; and (b) three independent ethernet ports communicatively coupled to the measurement circuitry, each independent ethernet port being configured to connect to a respective local area network (LAN) and to communicate the measured energy-related parameters to that LAN. A related system is also described.

Abstract: An adapter assembly is used to secure a base unit and a display unit to a panel, with the base unit including a housing, the panel including an opening formed in the panel, and the display unit including a body. The adapter assembly includes an adapter disposed between the base unit and the panel. The adapter includes a primary wall. One of the display unit and the adapter includes a formation that extends from the body of the display unit or the primary wall of the adapter, and the other of the display unit and the adapter includes a mechanism configured to engage and secure the display unit to the panel without disturbing a securement of the base unit to the adapter.

Abstract: An intelligent electronic device (100) for metering a characteristic of electricity that has a rear opening (214) and a side opening (216) in a housing of the device for accepting a connector of an expansion module through one or the other opening. The device can be configured with an integrated display module (120) that protrudes through a panel of an enclosure, and in this configuration, the expansion module connects to the device through the rear opening of the housing. The device can also be configured to be mounted on a DIN rail, and in this configuration, the expansion module connects through the side opening of the housing. The same module can be used in either configuration, without requiring that different versions of the module be made for the different configurations and without having to mount the device in an awkward orientation that makes it difficult to access external connections around the housing.

Abstract: Methods and devices for mounting a sensor are presented herein. A temperature sensor assembly for a capacitor bank is disclosed that includes two opposing substrates, and a plurality of contact temperature sensors attached to each substrate. Each temperature sensor is configured to directly contact a surface of one of the capacitor cans in the capacitor bank and therefrom generate a signal indicative of the temperature of the capacitor can. A biasing member attaches the two substrates together. The biasing member is configured to selectively contract, such that the width of the sensor assembly is less than the gap distance between adjacent sets of tandem capacitor cans and the sensor assembly can insert between the sets of capacitor cans, and expand, such that the width of the sensor assembly is greater than the gap distance and the sensor assembly is tensioned against and thereby secured between the sets of capacitor cans.
