Evaluate Flicker Levels Against Emission Limits​


Improve Power Quality with Flicker Evaluation

ETAP’s FlickerMeter evaluates flicker compliance against emission limits. Flicker calculations comply with IEC 61000-4-15, which is the standard for electromagnetic compatibility (EMC).
FlickerMeter App
FlickerMeter is part of the Power Quality applications in ETAP. FlickerMeter allows importing CSV-formatted data files and analyzes up to 20 signals at each run, to evaluate flicker compliance against emission limits.
Flicker calculations comply with IEC 61000-4-15 which is the standard for electromagnetic compatibility (EMC) and the calculation provides instantaneous, short-term (PST), and long-term (PLT) flicker indices based on a voltage waveform loaded into the calculator.
The purpose of this analysis is to determine the level of flicker in a voltage waveform originating from various starting and stopping actions of equipment and continuous time-varying loads within a system with, for example, induction machines or arc furnaces.
