Full Description

Scope

This guide covers 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, The guide includes recommendations for ventilated, nonventilated, and sealed dry-type transformers having impregnated insulation systems. For more specific recommendations for a particular transformer, the manufacturer of that transformer should be consulted.

Purpose

To provide users with a more accurate determination of how to load transformers while maintaining its integrity and to give user of transformers with epoxy windings a loading guide.
