24. Create a Detailed Harmonic Analysis
Click on CHART/HARMONIC ANALYSIS.
Then select the cycle of the waveform to be analyzed and click CREATE.
This chart will allow you to select the waveform of interest, the cycle of interest and
create a detailed harmonic analysis of the waveform. It can be viewed as either text or
as a bar chart. The user can also zoom into the bar chart. Using the detailed harmonic
analysis helps characterize waveforms. For example a 6 pulse converter can be
identified by the predominate level of 5th and 7th harmonics.
When analyzing current waveform harmonics the K factor can be viewed. This value
is used to select de-rated transformers. This verifies a transformer is selected that will
not overheat due to actual harmonic content.
