Harmonic distortion is an increasingly common power quality problem, and one of the most complex to analyze. Going beyond the total harmonic distortion to assess each individual harmonic takes time, but is sometimes required to track down the source, and also to determine a mitigation strategy. Harmonic bar charts show all harmonics at a glance, but give no trending information about how harmonics vary with time. The ProVision 3D harmonic graph shows all recorded harmonics vs. time, but can display too much information at once. Creating custom graphs in ProVision for each harmonic can take time, especially for 51 voltage and current sources.
