This disclosure relates generally to an energy metering assembly configured to measure current and voltage of a one or more primary conductors, the energy metering assembly comprising a core; a coil having a plurality of turns, the coil being positioned around the core when securing the core to the one or more primary conductors; a voltage sensor, the voltage sensor being configured to sense a voltage of a one or more primary conductors; and a controller coupled to the coil and the voltage sensor, the controller being configured to determine a voltage of the one or more primary conductors, determine a current of the one or more primary conductors, and responsive to determining the voltage and the current, determine the power carried by the one or more primary conductors.

System and method for calibrating a non-contact energy metering assembly

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.

Adapter assembly for mounting a display

Disclosed herein are embodiments of systems and methods for determining the state of health of a generator battery set and its ability to supply generator starter motor with start-up energy by capturing a profile of voltage across terminals of the battery during a supply of electrical energy from the battery to the starter and comparing the captured voltage profile to a reference voltage profile to determine if a difference between the captured voltage profile and reference voltage profile exceeds an acceptable amount.

Battery voltage profile monitoring during generator start

An intelligent electronic device () for metering a characteristic of electricity that has a rear opening () and a side opening () 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 () 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.

Power meter configured for rear and side expansion

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.

Sensor mounting methodology

A method, system and device for synchronizing a time period over which energy measurements are accumulated for an energy monitoring system including a plurality of energy monitoring devices is described. The method comprises transmitting a first radio frequency packet from a time reference device via at least a first and a second of the plurality of energy monitoring devices to a third of the plurality of energy monitoring devices. The method further comprises adjusting a time register within the third energy monitoring device based on the reception of the packet. The method further comprises accumulating a measure of energy consumption by the third energy monitoring device of a load coupled with the third energy monitoring device. The method further comprises transmitting the measure of energy consumption from the third energy monitoring device via at least a fourth and a fifth of the plurality of energy monitoring devices to a data aggregation device. The method further comprises identifying by the data aggregation device an aggregate measure of energy consumption consumed by the load over the time period.

An apparatus includes a first jaw () coupled to a second jaw () to form an opening () when the first jaw () and the second jaw () are closed. An aligning structure couples to at least one of the first jaw () and the second jaw (). A portion of the aligning structure may be disposed within the opening () and aligns a power line () to a sensor () disposed within the first jaw () and the second jaw ().

Aligning structure for a power line and sensor

A system and method for detecting and responding to device tampering in an Energy Management ('EM') device is disclosed. The EM device is provided with mechanisms to detect and indicate unauthorized tampering with the device. Further, in response to detected unauthorized tampering, the device may take actions to protect the integrity of data generated by the device as well as protect any confidential data stored within the device. Such actions may include preventing further device operation, generating warnings to the device owner/user, marking subsequently generated data as suspect, destroying stored confidential data, etc.

System and method for seal tamper detection for intelligent electronic devices

A sensor apparatus for measuring power parameters on a power conductor, such as a high voltage transmission line may include a corona structure, an electronics assembly and a conductor mountable device. The corona structure may define an outer boundary surrounding the electronics assembly and the conductor mountable device. The corona structure may shield the electronic assembly and conductor mountable device from a corona produceable with the power conductor. The conductor mountable device may be a power parameter measurement device, such as a current sensor assembly. The current sensor assembly may be a split-core design that includes multiple transformer cores. The electronics assembly and the conductor mountable device may powered from a line voltage suppliable on the power conductor. Data may be wirelessly transmitted and received with the sensor apparatus.

Current sensor assembly

Systems and methods are disclosed for accurately measuring delivered or supplied electrical energy over an extended range of values. In one embodiment, a meter for monitoring the energy at a remote site includes a current sensor for measuring the current supplied to or from the site, and a microprocessor that generates output readings with an enhanced accuracy over a wide range of outputs in response to digital samples received from the sensor. In a one implementation, the meter is configured to provide readings with an accuracy that satisfies the standards IEC 60687 1A 0.5S, IEC 60687 5A 0.5S, ANSI C12.20 Class 20 0.5, and ANSI C12.20 Class 2/10 0.5. In another implementation, the meter is configured to provide readings with an accuracy that satisfies the standards IEC 60687 1A 0.2S, IEC 60687 5A 0.2S, ANSI C12.20 Class 20 0.2, and ANSI C12.20 Class 2/10 0.2.
