Abstract: PURPOSE: A methods and an apparatus for oscillator compensation in electrical energy meter are provided to ensure a accuracy in measuring electricity by employing a first generator and second generator which compensates for an interval of electricity being blocked from an electronic meter. CONSTITUTION: A first clock signal is used for measuring time when power is applied to a meter and a second clock signal is used by the processor for measuring time when power has been removed from a meter. An accuracy of the first oscillator is compensated periodically in relation to a compensation factor stored in memory. In one embodiment, a processor includes a counter for counting from a first value to a second value in response to a first clock signal. In such an arrangement, the processor substitutes the first compensation factor for first value. The meter can further include a timer, wherein the processor substitutes the first compensation factor for the first value in response to a first timer. The processor also is shown to implement a process for compensating for a accuracy of the second oscillator. This process compensates for the accuracy of the second oscillator in relation to the first oscillator. To this end, the process calculates a second compensation factor. The second compensation factor is determined when power is applied to the meter, wherein after power has been removed and restored, the second compensation factor is used to compensate time measured in relation to the second oscillator during the period power had been removed.
