International Classification:

G01R 1100

US Classification:

324 74, 324142, 702 60

Abstract:

A metering module for use in a power circuit monitoring system including a circuit monitor having a processor for processing data related to power signals, said metering module comprising at least one sensor for sensing a predetermined property of a power signal and for producing a corresponding sensor signal, and a modular metering circuit for producing data corresponding to said sensor signal for input into said circuit monitor, wherein said metering module is selectively detachable and replaceable relative to said circuit monitor to permit one or more of testing, calibration and repair of said metering module thereby minimizing any interruption in operation of said circuit monitor.

Abstract:

A method for time reference compensation in a power metering system, the method comprising monitoring a time-dependent characteristic of incoming AC power over a predetermined local time interval, comparing the monitored characteristic over the predetermined local time interval with the expected value of the characteristic based upon the nominal frequency of the AC power, and calculating a correction to one or more of local real-time and time-based measurements of the power metering system, based on the comparing.

B67D 7/06

US Classification:

220200, 222183

Abstract:

A closure member for a shroud includes an annular wall and no more than one raised surface, interior of the annular wall, which extends upwardly beyond any other component of the closure member. The raised surface is configured to inhibit movement of a container both longitudinally and laterally when the annular wall is attached to a shroud with a container disposed therein.

Inventors:

Michael W. Pyle - Hermitage TN
David C. Carlson - Murfreesboro TN

Assignee:

Square D Company - Palatine IL

International Classification:

G01R 2106

US Classification:

364483

Abstract:

An improved metering unit is described which samples a power-related waveform and simultaneously captures its analog signal parameters for temperature and all phases of voltage and current, providing a more accurate and clearer waveform sample that effectively detects harmonics problems and does not require signal interpolation methods. The improved metering unit comprises signal conditioning circuitry interfacing with the power line for sensing temperature and all desired phases of voltage and current parameters of the waveform. The metering unit further comprises a processor having a timer output. The timer output controls track and hold circuitry and an A/D converter. The timer output places the track and hold circuitry in the hold mode to simultaneously capture temperature and all the desired phases of voltage and current of the waveform, and, at the same time, the timer output triggers the A/D converter to convert the captured analog signal parameters into digital sample values.
