ANSI/IEEE Std C57.91-1981 : IEEE Guide for Loading Mineral-Oil-Immersed Overhead and Pad-Mounted Distribution Transformers Rated 500kVA and Less with 65 C or 55 C Average Winding Rise / / Institute of Electrical and Electronics Engineers

• Pubblicazione: New York, New York : , : IEEE, , 1981
• Descrizione fisica: 1 online resource (26 pages)
• Disciplina: 621.317
• Soggetto topico: Electric transformers - Protection
• Sommario/riassunto: General recommendations for loading 65 degrees Centigrade-rise mineral-oil-immersed overhead and pad-mounted distribution transformers are covered. Recommendations for 55 degrees Centigrade-rise transformers are included because a substantial percentage of these transformers are still in service. The recommendations are based on winding hottest-spot calculations only. Other factors that may limit the permissible load to lower values are listed. A method to establish winding temperature and loss of life by nomographs is given.
