G01R 22/06
G01D 4/00
G01R 21/00
H04L 12/28

Abstract:

Embodiments of the invention provide an electric meter assembly including a meter support platform or base able to reversibly electrically couple to a transformer providing inputs including an AC power supply, phase voltage, and/or a phase current. Output of the meter support platform or base can be DC power, AC phase voltage signals and/or AC phase current. Further, a removable or portable meter can couple to the meter support platform or base and to an electric meter system including a meter core coupled to a wireless transmitter, an antenna, an integrated power sensor, and data meter front end. The system includes a data manager configured for electric service analysis including energy usage, and/or interval temperature, phase voltage, current and phase angle in real time, electric energy kWh and kVARh values in a user-specified period, wrong meter base installation detection, physical location of the removable or portable meter, and tamper detection.

H01R 13/502
H01R 24/76
G01R 22/06

Abstract:

Some embodiments include an electric meter assembly including a socket housing with a socket interface extending from a top side of the socket housing, and a removable or portable meter coupled to the socket interface. Further, the electric meter assembly includes at a strap coupled at one end to at least one side of the socket housing. The strap is configured and arranged to extend over at least a portion of the meter from one side of the socket to an opposite side of the socket. Some further embodiments include an electric meter assembly with a support platform including a coupled transformer and socket housing. The socket housing includes a socket interface extending from a top side of the socket housing, and a secondary housing enclosed within the socket housing. The secondary housing includes a CT shunt and a switch assembly including an actuator extending through the top side.
