Analysis of equivalent 10-Hz voltage flicker measurement using IEC flickermeter standard

This paper presents the analysis of the equivalent 10-Hz voltage flicker measurement ( Delta V
₁₀
) based on the IEC flickermeter standard. The Delta V
₁₀
method has been employed to evaluate voltage flicker for more than two decades in several Asian countries and not been updated since 1978. Therefore, a careful inspection from various aspects was made against the Delta V
₁₀
method. The results uncover the deficiencies in the reliability of the Delta V
₁₀
method for voltage flicker measurement.
