IEC 60034-2-1-2014 Rotating electrical machines - Part 2-1: Standard methods for determining losses and efficiency from tests (excluding machines for traction vehicles)

Language: English, FrenchInternational Standard IEC 60034-2-1 has been prepared by IEC technical committee 2: Rotating machinery.
This second edition cancels and replaces the first edition of IEC 60034-2-1, issued in 2007, as well as IEC 60034-2A, issued in 1974. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) The test methods are now grouped into preferred methods and methods for field or routine testing. Preferred methods have a low uncertainty and for a specific rating and type of machine only one preferred method is now defined.
b) The requirements regarding instrumentation have been detailed and refined.
c) The description of tests required for a specific method is now given in the same sequence as requested for the performance of the test. This will avoid misunderstandings and improve the accuracy of the procedures. In addition, for each method a flowchart shows the sequence of tests graphically.Scope
This part of IEC 60034 is intended to establish methods of determining efficiencies from tests, and also to specify methods of obtaining specific losses.
This standard applies to d.c. machines and to a.c. synchronous and induction machines of all sizes within the scope of IEC 60034-1.
