Limiting low frequency interharmonic distortion and voltage fluctuations is considered. Reference is made to recent activities in the standard review process and to research literature regarding this specific topic and related issues. Some recalls on the main low frequency interharmonic voltages effects are reported. Then, the problems related to the combined use of limits and assessment procedures...
Flicker is caused by the fluctuation of voltage that supplies the source of light. Such a fluctuations are accompanied by the existence of interharmonics. This paper summarizes the measurement of interharmonics accordant to IEC 61000-4-7 standard. Also included are the results of analysis of flickermeter signal chain for the input signal composed of two interharmonics. The relation between the Pst...
