IEEE 1276 1997 Edition, June 26, 1997 Guide for the Application of High-Temperature Insulation Materials in Liquid-Immersed Power Transformers
More info
Description / Abstract:
This guide provides technical information related to
liquid-immersed power transformers insulated with high-temperature
materials.
- Guidelines are provided for applying existing qualified high-temperature materials to insulation systems suitable for high-temperature liquid-immersed power transformers.
- Recommendations are made regarding the loading of high-temperature liquid-immersed power transformers.
- Technical information is provided for insulation-system temperature ratings and test procedures for qualifying new high-temperature materials as they become available.
No specific guidance is provided on insulating fluids other than mineral oil. This subject is to be covered in a future revision of this guide once more field experience is available using fluids other than mineral oil in combination with high-temperature solid materials.
Purpose
This guide is intended as a first step in the direction of standardizing the application of high-temperature insulation systems in transformers using insulation materials such as aramid papers, aramid transformerboards, high-temperature enamels, and hybrid systems that include both high-temperature materials and cellulose materials. It provides technical information for the transformer designer as well as for the transformer user.
