BS EN 60034-1:2004 - Page 3

Rotating electrical machines - Part 1: Rating and performance

Requirements for the rating and performance of rotating electrical machines.

This part of EN 60034 is applicable to all rotating electrical machines except those covered by other IEC standards, for example, IEC 60349.

The major changes introduced in this European Standard from the previous edition are:

- new requirements for a.c. generators to supply non-linear circuits;

- new requirements for routine tests;

- test voltages of auxiliaries tables;

- total harmonic distortion for synchronous machines;

- protective earthing for machines;

- tolerance on efficiency tables;

- electromagnetic compatibility.

Machines within this standard may also be subject to superseding, modifying or additional requirements in other publications, for example, IEC 60079, and

IEC 60092.

This European Standard supersedes BS EN 60034-1:1998 which will be withdrawn on 1 June 2007. It also replaces BS 4999-143:1987 regarding the definitions of routine tests. BS 4999-143 will be revised to cover only the “basic” tests.

This standard includes the following cross references:
