Graphical Methods For Presenting Time-Varying Harmonics

• Several tools are available for reducing large quantities of data in order to obtain indices and reporting formats, like IEC 61000-4-30 and the recommendations by CIGRE C4.112. But those methods often suffer from a surplus of information or a lack of information. In this context, this paper introduces a number of alternative graphical methods and visualization techniques and illustrates those using real measurements. The main objective of this work is to show the most appropriate tools to present the variations of harmonics at time-scales from a few cycles through a few years.
