Title Rotating electrical machines - Part 4: Methods for determining synchronous machine quantities from tests
Project Number 21127
Abstract/Scope IEC 60034-4:2008 applies to three-phase synchronous machines of 1 kVA rating and larger with rated frequency of not greater than 500 Hz and not less than 10 Hz. The main changes with respect to the previous edition are as follows: - removal of certain tests for lack of relevance in current practise; - addition of provisions for tests on machines with brushless excitation; - addition of a table of test methods indicating preferred tests and cross-references.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
