Abstract:
This work shows the comparison between a harmonic meter based on a digital multimeter digitizing function and a comercial electricity harmonics standard. Details of the algorithm with remarks about how signal processing techniques were applied to avoid some pitfalls and improve results reliability are shown. Some techniques used to achieve better spectrum resolution and a method to measure harmonic phase will be also shown, with graphical visualizations and algorithm description.
