Abstract
Methods and apparatus for metering electrical energy are disclosed in an electronic meter. Such meter includes a first processor for determining electrical energy from voltage and current signals and for generating an energy signal representative of the electrical energy determination and a second processor for receiving the energy signal and for generating an indication signal representative of said energy signal. An option connector is connected to the first and second processors, whereby the energy signal is provided to the option connector and a communication connection is provided between the option connector and the second processor. It is preferred for the option connector to be provided power signals such used by the meter in order to power any electronic components which may be connected to the option connector. It is also preferred to provide the option connector with certain operation signals such as a power fail signal, a master reset signal, an end of demand signal, and a KYZ signal. It is still further preferred to provide the option connector with the potential to communicate with various components of the meter, such as serial data communication, communication signals transmitted and received through an optical port and display signals. It is also preferred for the first processor to include a comparator, connected to receive a precision voltage and a reference voltage, wherein a comparator signal is generated whenever the reference voltage exceeds the precision voltage.
