Category: Power Quality
Daily Profiles are used to spot daily trends in voltage, current, power factor, etc. An entire recording session is combined to form the “average” 24-hour day, which is then plotted on a graph like a stripchart. Power quality issues are usually not addressed with Daily Profiles (except perhaps consistently low or high line voltage or harmonic distortion). Rather, average line conditions such as regulation voltage, load current, etc. are profiled. This paper explains daily profiles and their uses, as well as how to create a daily profile graph in Provision.
The Daily Profile graph is one of several different graph types available with ProVision, PMI’s free power quality analysis software. Provision allows you to create ten different types of daily profile graphs: RMS Voltage, RMS Current, Voltage THD, Current THD, Real Power (Watts), Apparent Power (VA), Reactive Power (VAR), Phase Angle, Power Factor, and Displacement Power Factor.
