IEC 60034-15: 2025 relates to AC machines incorporating form-wound stator coils that are intended to be connected to a standard grid supply. It specifies the test procedures and voltages to be applied to sample coils, as well as routine tests performed on coils mounted in the stator core. The purpose of this document is to show the ability of a stator winding to resist voltage transients originating from the grid the machine is connected to. Annex A gives further information. The stator windings and coils for converter-fed machines are excluded from the scope of this document. This document is not intended for use on complete windings since it is difficult to determine when the turn insulation has failed due to the test.全文を表示する
This fourth edition cancels and replaces the third edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- harmonize the standard test levels with IEEE Std 522TM 2;
- introduce an enhanced surge impulse voltage withstand level;
- introduce the option to test up to the point of electrical breakdown;
- improve the evaluation of the recorded impulses in case of oscillations and overshoot;
- indicate that converter fed machines are excluded from the scope;
- provide guidance on the execution of impulse tests.
