IEEE Recommended Practice for the Preparation of Test Procedures for the Thermal Evaluation of Insulation Systems for Electrical Equipment
This recommended practice provides criteria for the preparation of test procedures for accelerated thermalaging of insulation systems and for the specification of tests based on conditions of use. The objective ofthese test procedures is to provide for the functional evaluation, by test, of insulation systems for electricalequipment. The evaluation of insulating materials and simple combinations thereof is provided for by aseparate material test guide, IEEE Std 98(TM)-2002.1For a detailed discussion of the principles on which this recommended practice and IEEE Std 98-2002 arebased, see IEEE Std 1(TM)-2000. Tests based on IEEE Std 98-2002 may be considered as preliminary testsfor insulation system evaluation, but should not be used as accepted tests for the classification of systems.
Purpose
This recommended practice provides a general form for the preparation of test procedures and suggests thepoints to be considered by technical committees in the preparation of specific instructions for the thermalevaluation of insulation systems for equipment.
Abstract
Revision Standard - Active.Revision of IEEE Std 99-1980. A general form is provided for the preparation of test procedures. Points to be considered by technical committees in the preparation of specific instructions for the thermal evaluation of insulation systems for electric equipment are suggested. The test procedures involve accelerated thermal aging of insulation systems and specify tests that the committees deem pertinent, based on conditions of use. The objective of the procedures is to provide for the functional evaluation, by test, of insulation systems for electric equipment.
