IEC 60034-28-2012 Rotating electrical machines - Part 28: Test methods for determining quantities of equivalent circuit diagrams for three-phase low-voltage cage induction motors

Language: English, French
International Standard IEC 60034-28 has been prepared by IEC technical committee 2: Rotating machinery.
This second edition cancels and replaces the first edition published in 2007. This edition constitutes a technical revision.Scope
This part of the IEC 60034 series applies to three-phase low-voltage cage induction motors of frame numbers 56 to 400 as specified in IEC 60072-1.
This standard establishes procedures to obtain values for elements of single phase equivalent circuit diagrams from tests and defines standard elements of these diagrams.
