Utility engineers have long used the "GE Curve" for determining allowable flicker levels on their electrical systems. They have grown accustomed to the procedure as well as developed tools to simplify the calculation process. With the recent approval of IEEE 1453-2004, another option exists for the determination of flicker compliance. This paper will compare the use of both methods to allow the reader to see the differences as well as the similarities. The accompanying presentation will also provide illustrated results for the use of each method. This will hopefully encourage others to adopt this newer method.
