Owning Palette: Power Quality VIs
Requires: Electrical Power Toolkit. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.
Use the Events VIs to detect voltage dips, swells, interruptions, and rapid change events as defined in IEC 61000-4-30:2008.
| Palette Object | Description |
|---|---|
| Rapid Voltage Changes | Detects rapid RMS voltage changes between two steady state conditions according to IEC 61000-4-30:2008. The variation in voltage must not exceed the voltage dip threshold, the voltage swell threshold, or the thresholds that contain both voltage dip and voltage swell. EN 50160:2007 defines default threshold values. You also can specify custom threshold values.
This VI supports measuring single-bus single-line or multiple-bus single-line systems. |
| Voltage Dips, Swells, and Interruptions | Detects RMS voltage dips, swells, and interruptions, according to IEC 61000-4-30:2008. EN 50160:2007 defines the default threshold values. You also can specify custom threshold values. You can use EN 50160:2007 to evaluate voltage events that this VI detects.
