IEEE C57.96-1999 IEEE Guide for Loading Dry-Type Distribution and Power Transformers

standard by IEEE, 10/29/1999

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.
