IEC 60034-4-2008 Rotating electrical machines - Part 4: Methods for determining synchronous machine quantities from tests

Language: English, FrenchInternational Standard IEC 60034-4 has been prepared by IEC technical committee 2: Rotating machinery.
This third edition cancels and replaces the second edition published in 1985 and its amendment 1 (1995). This edition constitutes a technical revision. The main changes with respect to the previous edition are listed below:
– Tests described in Supplement A of the previous edition were partly removed for lack of relevance in current practise.
– Provisions were made for tests on machines with brushless excitation.
– A table of test methods indicates preferred tests, and a test cross-reference is provided.
– The conventional two-axes salient-pole machine model description was added in an Annex.Scope
This part of IEC 60034 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.
Most of the methods are intended to be used for machines having an excitation winding with slip-rings and brushes for their supply. Synchronous machines with brushless excitation require special effort for some of the tests. For machines with permanent magnet excitation, there is a limited applicability of the described tests, and special precautions have to be taken against irreversible demagnetization.
Excluded are axial-field machines and special synchronous machines such as inductor type machines and transversal flux machines.
It is not intended that this standard be interpreted as requiring any or all of the tests described therein on any given machine. The particular tests to be carried out shall be subject to agreement between manufacturer and customer.
