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 →

The Symmetrical Components tool is an Excel Workbook that shows the breakdown of an arbitrary three-phase set of vectors into its Symmetrical Components. This tool is implemented in Excel in order to facilitate its use by students and professional engineers alike. The spreadsheet takes the Magnitude and Angle of each of the vectors as an input as shown in the image below. Using this information, the Cartesian coordinates of the origin and end of each vector are calculated to be used in the chart. After this, the symmetrical components are calculated for Positive, Negative and Zero sequence. All of these are then also reported inRead More →
