ANSI C57.12.56 - Standard Test Procedure for Thermal Evaluation of Insulation Systems for Ventilated Dry-Type Power and Distribution Transformers
January 1, 1986 - IEEE

Foreword (This Foreword is not a part of ANSI/IEEE C57.12.56-1986, IEEE Standard Test Procedure for Thermal Evaluation of Insulation Systems for Ventilated Dry-Type Power and Distribution Transformers.) This standard was developed to provide a method for evaluating insulation...

November 1, 1956 - IEEE

PREFACE For many years, temperature limits for electric apparatus have been founded upon classification of insulating materials by broad general definitions based upon chemical composition1. Recently, it has become apparent that this method no longer meets the needs of the industry and that a new...
