IEC 60034-16-1-2011 Rotating electrical machines - Part 18-32: Functional evaluation of insulation systems - Test procedures for form-wound windings - Evaluation by electrical endurance

Language: English, French
International Standard IEC 60034-18-32 has been prepared by IEC technical committee 2: Rotating machinery.
This first edition cancels and replaces IEC/TS 60034-18-32, published in 1995 and constitutes a technical revision.
The main technical changes with regard to the previous technical specification are as follows.
a) simplification of clauses;
b) reduction in the number of test procedures;
c) inclusion of full bars and coils as test objects;
d) a new clause dealing with failures and failure criteria.Scope
This part of IEC 60034-18 describes test procedures for the evaluation of electrical endurance of insulation systems for use in a.c. or d.c. rotating electrical machines using form-wound windings. The test procedures are comparative in nature, such that the performance of a candidate insulation system is compared to that of a reference insulation system with proven service experience. The test procedures are principally directed at the insulation systems in air-cooled machines but may also be used for evaluating parts of the insulation systems in hydrogen cooled machines. Note that the qualification procedures of inverter duty insulation systems for form-wound windings can be found in IEC 60034-18-42.
