IEEE Trial Use Guide for loading Mineral-Oil Immersed Power Transformers Rated in Excess of 100 MVA (65 Degree C Winding Rise)

This guide covers general recommendations for loading mineral-oil-immersed power transformers manufactured in accordance with ANSI/IEEE C57.12.00-1980 [lP and having a maximum nameplate rating in excess of 100 MVA (three phase) or 33+ MVA (single phase). Such transformers have an average winding rise of 65 DC maximum and a hottestipot rise of 80 DC maximum at rated load. NOTE: When this guide is to be used for transformers purchased prior to publication of the guide, the applicability of 2.5 and 4.3 should be checked with the manufacturer. Also see Appendix D
