metadata.artigo.dc.description.abstract: This paper provides an in-depth analysis of the methodologies proposed by the IEC 61000-4-7 and IEC 61000-4-30 standards for the supraharmonic frequency range. The paper presents the stat-of-the-art concerning supraharmonics and describes the existing standardized measurements for supraharmonics. The different ways of performing the measurements proposed by such standards are compared. The main contribution and novelty of the paper are the comparative analysis of the standardized measurement methods which considers both efficiency and computational complexity of them. Analyzes considering real signals, a real time signal, a time-varying synthetic signal and the influence of the noise level for the methodologies proposed by the IEC 61000-4-7 and IEC 61000-4-30 standards were performed. Finally, alternative ways of measuring supraharmonics are suggested. One may conclude that the method described in IEC 61000-4-30 showed to be less immune to noise and less complex (in terms of mathematical operations required during processing) than that described in the IEC 61000-4-7, but loses accuracy in estimating high-amplitude supraharmonic components.
