Harmonic analysis tools such as ETAP, EasyPower, CYME, and SKM are indispensable tools that aid engineers with the evaluation and mitigation of harmonics on industrial and utility power systems. However, when these tools are presented with bad input data or the program output is interpreted improperly it can lead to incorrect system designs.

In this IAS Session, NEPSI will provide the basics of harmonic analysis, (the ability to verify the output of your analysis program), the key steps in performing harmonic analysis, with discussion on input data (extent of modelling, impedance data, harmonic data, modeling of stray  capacitance, interharmonics, and non-characteristic harmonics), data validation, model validation, filter design, resonance, and interpretation of program outputs, and more.

If you don’t understand the basics, you cannot trust the output of your harmonic analysis program.
