How Does IEEE 1453 compare to the GE curve in evaluating flicker compliance

The ldquoGE Curverdquo has been in use for many years by most utilities as their sole criteria for determining the serviceability of connected loads to their electrical system. This long term usage has bred familiarity with both the method and the criteria. In recent years, the IEEE Voltage Flicker TF undertook the task of adopting the IEC method of determining flicker. This was done so as to bring about International consensus concerning flicker criteria as well as noting the deficiency of the ldquoGE Curverdquo method compared to the advantages of the IEC method. As a result, IEEE 1453-2004 was adopted as a better method to address flicker limits. As the differences in the two methods has been documented by others already, this paper will just discuss differences in the application of the two methods in order to encourage others to use this more beneficial method.
