摘要： An apparatus for disposing a meter register in a default mode of operation includes a microcontroller coupled to a programmable non-volatile memory for automatically disposing the meter register in a self-programmed state when the electrical meter containing the meter register is installed for the first time. The self-programmed state is a functional default state and provides a monitoring utility company with accurate customer billing information from the time of installation. Accordingly, a technician responsible for installing the meter in the field need not be familiar with the techniques for programming the meter. If a mode of operation other than the default mode of operation is preferred, the microcontroller can be accessed for disposing the meter in a time-of-use and demand mode of operation or a demand only mode of operation. The microcontroller also provides means for retaining a programmed state of the meter register in the event of a power outage. Thus, when power is again supplied to the meter after an outage, the meter register is again disposed in the last programmed state prior to power failure.

摘要： A method of processing binary characters received by an electrical energy meter includes the step of generating a clock signal internal to the meter so that asynchronously received serial data can be processed, even though a synchronization clock signal does not accompany the serial data. The method includes the steps of detecting receipt of a first of a string of binary input characters at a serial input/output port of the meter, and then sampling the detected first character by generating a respective first clock signal which is phase-synchronized with a least significant bit of the first character. These steps are then repeated in sequence for each subsequently received character in the string. The sampled characters can be temporarily stored in meter hardware such as a register and written to memory such as programmable read-only or random-access memory. Phase-synchronization between the sampling clock signals and each of the respective characters is achieved even though the data rate of the binary string (e.g., 9600 bits/sec) is unequal to an integer fraction of the frequency of the main crystal oscillator of the meter (e.g., 4.19 MHz), which controls meter operations.

摘要： An apparatus and method for measuring electrical energy and quadergy and for performing line frequency compensation includes a compensation integrated circuit for adjusting the determined reactive load quadergy, based on variations between the actual line frequency and the rated line frequency of the meter. Reactive load quadergy is determined by phase-shifting the line voltage by a fixed time interval, based on the rated line frequency of the meter. The determined reactive load quadergy is adjusted to compensate for variations in line frequency. Because the determined reactive load quadergy is output by an electric meter as a continuous pulse train, adjustment to the determined reactive load quadergy is performed by adding or subtracting state changes from the pulse train and then registering the adjusted reactive load quadergy.
