ABSTRACT:
The electric parameter metering machine comprises electric parameter pickup circuitry for sensing the instantaneous analog amplitude value of a electric parameter waveform in at least one phase in an electric power distribution system at selected time intervals during each full cycle, an A/D converter for converting the analog amplitude values to digital signals and signal processing circuitry including a memory for storing the digital signals. The signal processing circuitry includes a microprocessor operable to apply a conventional waveform analysis technique to the digital signal information collected with respect to a selected number of cycles of the electric parameter waveform to obtain an instantaneous RMS value of the electric parameter and operable to process a sequence of instantaneous RMS electric parameter values at discrete time intervals to obtain time averaged or demand electric parameter values. A visual display device is coupled to the signal processing circuitry and a pushbutton control panel is coupled to the signal processing circuitry for enabling an operator to operate pushbuttons to provide a digital readout of either instantaneous RMS, demand, or peak demand values on the visual display device.
