Single- and three-phase transformers rated601 V to 15 000 V for the highest voltage winding and up to 2500 kVA (self-cooled rating) arecovered. Because of the conservative approach used in the development of this new standard fornew transformers, the end-point criteria cannot be used for in-service transformers.IEEE Std 638-2013 (Revision of IEEE Std 638-1992) - Redline: IEEE Standard for Qualification of Class 1E Transformers for Nuclear Power Generating Stations - RedlineIEEE Std 638-2013 DesignMethodologyNuclear power plantsDesignMethodology.Nuclear power plants.621.48NjHacINjHaclDOCUMENT996279417803316IEEE Standard for Qualification of Class 1E Transformers for Nuclear Power Generating Stations - Redline3647528UNISA
