IEEE Guide for Loading Dry-Type Distribution and Power Transformers

The guide covers general recommendations for the loading of dry-type distribution and power transformers that have 80 degrees C, 115 degrees C, and 150 degrees C average winding rises and insulation systems limited to 150 degrees C, 185 degrees C, and 220 degrees C maximum hottest-spot operating temperatures respectively., The guide includes recommendations for ventilated, nonventilated, and sealed dry-type transformers having impregnated insulation systems. If the user desires more specific recommendations for a particular transformer, the manufacturer of that transformer should be consulted.<
