Calculating a new reference point for the iec‐flickermeter

Abstract

Modern multicycle-controlled equipment produce voltage fluctuations with repetition rates much higher than the highest frequency for type testing the IEC flickermeter under the standard IEC 61000-4-15. In order to equalize all flickermeters it is necessary to add an additional reference point for 33'/? Hz to the standard. The amount of d/%-values will be evaluated. Reference values for 120- V/60-Hz- and 230- V/60-Hz systems have been added.
