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 Aggregation VIs to aggregate data at a specific interval according to Class S of IEC 61000-4-30:2008.

Palette ObjectDescription
Custom AggregationCalculates the aggregated minimum, maximum, and averaged or RMS value of an input signal for a specified aggregation interval, according to Class S in IEC 61000-4-30:2008. There is no overlap between aggregation intervals. This VI automatically restarts accumulation at the beginning of the next time interval after the previous interval expires. You must manually select the polymorphic instance you want to use. This VI supports measuring single-line and multiple-line systems except the DBL instance. Use the DBL instance to measure one channel on one line at one time.
EN50160 AggregationCalculates aggregated values of power quality parameters for specific intervals. You use the aggregated values for further evaluations according to EN 50160:2007. The aggregation methods are compliant with Class S in IEC 61000-4-30:2008. The aggregation is based on a 10-cycle time interval for a 50 Hz power system or 12-cycle time interval for a 60 Hz power system. There is no overlap between aggregation intervals. This VI automatically restarts accumulation at the beginning of the next 10/12-cycle time interval after the previous interval expires. You must manually select the polymorphic instance you want to use. This VI supports measuring single-bus single-line or multiple-bus single-line systems.
