Electromagnetic compatibility (EMC) - Limits. Limitation of voltage fluctuations and flicker in low-voltage power supply systems for equipment with rated current greater than 75 A Ingestion-build-48974 Any tunnel lining using material1 Scope This part of IEC 61000 deals with emission of disturbances due to voltage fluctuations and flicker. The recommendations in this Technical Specification are applicable to electrical and electronic equipment that has a rated input current exceeding 75 A per phase and is intended to be connected to a public low voltage a. c. distribution system. Recommendations that specify information enabling a supply authority, manufacturer, or consumer to
