Waveform Capture Two cycles (64 samples/cycle) of voltage and current waveforms can be captured and displayed on a PC using the EnerVista PQMII Setup Software or third party software. Distorted peaks or notches from SCR switching provides clues for taking corrective action. Waveform capture is also a useful tool when investigating possible wiring problems due to its ability to display the phase relationship of the various inputs. The waveform capture feature is implemented into EnerVista PQMII Setup Software as shown below. Select the Actual > Power Analysis > Waveform Capture menu item. The EnerVista PQMII Setup Software will open the Waveform Capture dialog box.

Select the buttons on the left to display the desired waveforms. The waveform values for the current cursor line position are displayed to the right of the selected buttons. Numerical values are displayed directly below the button.

Harmonic Analysis 

Non-linear loads such as variable speed drives, computers, and electronic ballasts can cause harmonics which may lead to problems such as nuisance breaker tripping, telephone interference, transformer, capacitor or motor overheating. For fault diagnosis such as detecting undersized neutral wiring, need for a harmonic rated transformer or effectiveness of harmonic filters; details of the harmonic spectrum are useful and available with the PQMII and the EnerVista PQMII Setup Software. The EnerVista PQMII Setup Software can perform a harmonic analysis on any of the four current inputs or any of the three voltage inputs by placing the PQMII in a high speed sampling mode (256 samples/cycle) where it will sample one cycle of the user defined

parameter. EnerVista PQMII Setup Software then takes this data and performs a FFT (Fast Fourier Transform) to extract the harmonic information. The harmonic analysis feature is implemented into EnerVista PQMII Setup Software as shown below. Z Select the Actual > Power Analysis > Harmonic Analysis > Harmonic Spectrum menu item. The EnerVista PQMII Setup Software can display the Harmonic Analysis Spectrum window including the harmonic spectrum up to and including the 62nd harmonic. Z Enter the trigger parameter for the Select Trigger setting. Z Click the Select button for the Trigger setting. The Waveform capture window will appear.
