ABSTRACT:
A metering device of a power substation and method are provided for operating on a secondary analog waveform output by a transformer assembly receiving a primary waveform. The method includes stepping down the secondary waveform and generating a corresponding output signal; operating on the corresponding output signal for generating a corresponding first digital signal having a value proportional to the corresponding output signal and within a first range; and operating on the corresponding output signal for generating a corresponding second digital signal having a value proportional to the corresponding output signal and within a second range. The method further includes processing the first digital signal and outputting a corresponding first output signal; processing the second digital signal and outputting a corresponding second output signal; processing the first and second output signals; and generating output corresponding to the processing of the first and second output signals.
