Revision Standard – Inactive – Superseded. Reaffirmed 2004. General recommendations for the loading of dry-type distribution and power transformers that have 80 C, 115 C, and 150 C average winding rises and insulation systems limited to 150 C, 180 C, and 220 C maximum hottest-spot operating temperatures, respectively, are covered in this guide. Recommendations for ventilated, nonventilated, and sealed dry-type transformers having impregnated insulation systems are included.<\/p>\n
