Rotating Electrical Machines Part 18: Functional Evaluation of Insulation Systems Section 21: Test Procedures for Wire-Wound Windings - Thermal Evaluation and Classification
|Publication Date:||1 July 1992|
|ICS Code (Rotating machinery in general):||29.160.01|
This section of IEC 34-18 gives test procedures for the thermal evaluation and classification of insulation systems used or proposed for use in wire-wound alternating current (a.c.) or direct current (d.c.) rotating electrical machines. The test procedures are comparative in that the performance of a candidate insulation system is compared to that of a reference insulation system with proven service experience.
Section 21 shall be used in conjuction with Section 1.
