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.
