Owning Palette: Advanced VIs
Requires: . This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.
Use the Harmonics VIs to preprocess the voltage and current signals and then to perform harmonic analysis.
| Palette Object | Description |
|---|---|
| Build Data Blocks | Builds even-angle-spaced voltage and current signals into data blocks. |
| Harmonic Power | Calculates the harmonic power values from the phase voltage spectra and the current spectra. |
| Harmonic Spectrum | Calculates the fast Fourier transform (FFT) spectra from the resampled signals. This VI returns FFT spectra as complex spectra up to maximum harmonic order. |
| Resampling for Power Measurement | Resamples even-time-spaced voltage and current signals into even-angle-spaced signals for harmonic analysis, according to the trigger times that you specify. |
| THD | Calculates the total harmonic distortion (THD), harmonic distortion factors, and total values from voltage harmonic spectra, current harmonic spectra, or harmonic spectra that contain both voltage and current. |
