Appl. No.:

09/491379

International Classification:

G01K 1500

US Classification:

702 99

Abstract:

The phase shift in an electronic energy meter is compensated for by obtaining temperature and frequency readings in the meter and using these readings in a digital signal processor (DSP) residing within the electronic energy meter. The frequency and temperature compensation is performed to each phase calibration and the result is stored in the DSP. To reduce the possible influence of noise in the system, the compensated DSP values are filtered to provide a smoothing of the data.

International Classification:

H02B001/00

US Classification:

361668, 361720, 361748, 361736, 200284

Abstract:

An electronic energy meter and its package is described in which the meter package has a reduced number of parts, and the main circuit board assembly has the metering electronics on board, thereby eliminating the need for flying leads and point-to-point wiring within the package. The energy meter includes a first enclosure portion, a circuit board assembly for performing metering functions, a partial terminal block, and a second enclosure portion. The first and second enclosure portions are mateable with each other to form a meter package, in which the circuit board assembly and partial terminal block are at least partially contained within the meter package.

International Classification:

H01H 21/78

US Classification:

200 11R, 200 11 TC, 200336

Abstract:

An actuator switch for use in an electronic energy meter has a reduced number of parts, and can be used to actuate multiple concealed switches. An actuator switch includes an inner actuator portion having ribs separated by at least one gap, and an outer housing with a locking-tab, where the locking-tab corresponds to at least one gap for interlocking.
