AN IEC 61000-4-30 CLASS A POWER QUALITY MONITOR WITH A FLICKER METER BASED ON HILBERT TRANSFORM

Andrés E. Legarreta, Javier H. Figueroa
  • Abstract:
    This paper provides a novel analysis to implement a demodulation technique based on discrete Hilbert transform. Running on a DSP floating point architecture mounted in the power quality instrument PQ1000 ECAMEC fulfills the requirements of IEC61000-4-30, Class A category, over all the electrical measured parameters. Several analysis of optimal filter design and performance of signal processing are presented.
