This paper discusses the issues of assessing the influence of external distortion sources on the functioning of a shunt passive harmonic filter. In this study. we evaluated the overload of a passive harmonic filter based on determining the contributions of distortion sources. A method was proposed for assessing the contributions of distortion sources. https://www.diegojavierfares.com/mega-offer-Classic-Premier-Navy-Drapery-Fabric-by-Premier-Prints-30-Yard-Bolt-super-offer/
