It is based mostly on aging of the winding insulation. Loading of transformers larger than 100 MVA may be limited by factors other than insulation aging such as stray flux, etc. When it is known that such limitations do not exist and insulation aging rather than oil temperature, gassing, tank heating, etc., is the controlling factor, this guide may be used. This guide may also be used for askarel filled transformers. 517 $aANSI/IEEE Std C57.92-1981: IEEE Guide for Loading Mineral-Oil-Immersed Power Transformers Up to and Including 100 MVA with 55 C or 65 C Average Winding Rise 606 $aElectric apparatus and appliances$xProtection 606 $aElectric transformers 615 0$aElectric apparatus and appliances$xProtection. 615 0$aElectric transformers. 676 $a621.314 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a9910135768103321 996 $aANSI$92072434 997 $aUNINA
