Harmonic Analysis View
Perform harmonic analysis (up to 50th) on the output voltage and output current. A simplified measurement method is used, so this method does not conform to standards such as IEC.
- The measured values of 1st to the 50th harmonic are rms values.
- The phase degree is the phase difference (±180 deg) from the fundamental voltage waveform.
| 1 | Select the Output Type (Voltage or Current) to be displayed on the harmonic list. | |
| 2 | Display All harmonics , Odd order number harmonics only, or Even order number harmonics only. | |
| 3 | Total Harmonic Distortion(THD) is the ratio of the harmonic components up to the 50th harmonic relative to the fundamental component. | |
| 4 | Enable or disable all outputs. | |
| 5 | Click Poll Harmonic Data to display the harmonic data on the list. Select the Continuous polling check box to poll in the harmonic data continuously. To stop the Continuous polling, click Stop Harmonic Data Poll. | |
| 6 | View the harmonic data in a bar chart. Click again to hide the bar chart. | |
| 7 | Display the harmonic list. This application is able to show harmonic up to the 50th order, use the scroll bar to view all the harmonic orders. |
Bar Chart
View harmonic data as a bar chart.
Groups are plotted on the horizontal axis (x-axis) using the harmonic order numbers, voltages/currents are plotted on the vertical axis (y-axis).
