Abstract

PURPOSE: To make it possible to obtain an accurate and equivalent flicker value even if voltage variation in an AC voltage connecting to a variable load is any one of single sine-wave variation, distorted-wave variation and irregular variation, by processing variation in the effective value of an AC power supply.
CONSTITUTION: Variation in the effective value of AC power supply 1 is detected 2 and squared 6 after passing through filter 3 equivalent to flicker visual sensitivity characteristics; and a mean integral value within a certain time is calculated 7 from the above output and the square root of this output is calculated 8, thereby recording or displaying accurate and equivalent flicker value ΔV10 of 10Hz. In this case, gain change-over circuit 9 which can be changed over according to the kind of variation in effective value is provided behind a method of calculating 8 the square root.
