The Harmonics Visualiser tool is an Excel workbook that presents the vectorial and sinusoidal representation of a system of harmonic components. The magnitude of the vectors can be entered on the left-side of the graphs and the angles are calculated automatically depending on the order of the harmonic component. The vectors are presented as a three phase system whilst the sinusoidal graph is referenced to Phase A or Red Phase. The sinusoidal chart also shows a summation of all the harmonic components into the final resulting wave form. The tool includes an animation function in which the vectors are rotated through a 360 degree cycleRead More →
