Abstract
An electronic utility meter includes a sensor module and a removable measurement module. The sensor module connects to the electrical system of a facility and includes voltage and current sensors. The voltage and current sensors is operable to receive voltage and current signals from the electrical system and generate measurement signals therefrom. The sensor module further includes an electrically safe interface. The removable measurement module includes a measurement circuit operable to receive measurement signals and generate energy consumption data therefrom. The measurement module also includes a device for communicating information relating to the energy consumption data. The electrically safe interface of the sensor module operably connects the voltage and current sensors to the measurement circuit, and further prevents physical contact of a human operator with the received voltage and current signals from the electrical system when the measurement module is removed from the sensor circuit.
