IEC 60034-2-2-2010 Rotating electrical machines. Part 2-2: Specific methods for determining separate losses of large machines from tests - Supplement to IEC 60034-2-1

Language: English, FrenchInternational Standard IEC 60034-2-2 has been prepared by IEC technical committee 2: Rotating machinery.Scope
This part of IEC 60034 applies to large rotating electrical machines and establishes additional methods of determining separate losses and to define an efficiency supplementing IEC 60034-2-1. These methods apply when full-load testing is not practical and result in a greater uncertainty.
The specific methods described are:
– Calibrated-machine method.
– Retardation method.
– Calorimetric method.
