IEEE Std. 141 Flicker Curve vs. IEEE 1453 Flicker Meter
In this whitepaper I describe and compare two of the IEEE Flicker standards, the older standard 141 (the GE Flicker Curve), and the newer IEEE 1453 (Flicker Meter standard). The…
Voltage Notching in IEEE Std. 519-2014
In this white paper, I cover the new IEEE Std 519-2014 limits for voltage notching, how these limits are calculated, and how to use ProVision to make the notch measurements.…
Checking IEEE 519 Compliance with ProVision
IEEE standard 519 was first released in 1982 and was then updated in 1992. It defines limits on total harmonic distortion (THD) as well as total demand distortion (TDD) with…
Understanding IEEE IEC Flicker Processing
Flicker measurement has improved dramatically with the advent of the flicker measurement techniques described in IEEE-1453/IEC61000-4-15. It is a feature found in many power quality monitors that makes flicker measurement…
Understanding IEEE Flicker, IFL, Pst, Plt
This white paper covers and explains three of IEEE's most common Flicker definitions: IFL, Pst and Plt. The GE Flicker Curve and how other measurements standards compare to the GE…
