Meet current harmonics limits – challenges and solutions
Contemporary Issues in Economy and Technology - CIET 2024 - conference proceedingsDistortion of mains current caused by non-linear loads creates harmonics that can significantly affect the the overall system efficiency and particularly power factor. This paper explores several methods of higher harmonics mitigation according to the limits specified in standards IEC 610000-3-2 and IEC-5555-2 and in the equivalent European standard EN
