Application of the GE Flicker Curve

Application of the GE Flicker Curve

Learn about the origin of the GE Flicker Curve and how to apply it using PMI tools.


The GE Flicker, developed by General Electric in the 1930’s, is one of the oldest and most common flicker standards used today.


The GE Flicker Curve is based on studies done on a correlation of human perception of light flicker in reference to voltage fluctuation over time.


All current PMI recorders have the capability of generating Flicker Reports and use the GE Flicker Curve as bases for the default trigger settings. Some recorders are also setup to record other more recent flicker standards. Since light flicker is very subjective, a you can always modify the recorder’s Flicker Report settings to be more or less sensitive than the default GE Flicker Curve.


The PMI Recorder’s GE Flicker Report is a very useful tool for documenting and tracking down the cause of voltage fluctuations that create annoying light flicker for utility customers.
