Rotating electrical machines - Part 2-2: Specific methods for determining separate losses of large machines from tests - Supplement to IEC 60034-2-1
|Publication Date:||1 June 2010|
|ICS Code (Rotating machinery):||29.160|
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.
NOTE In situ testing according to the calorimetric method for full-load conditions is recognized.
The specific methods described are:
- Calibrated-machine method.
- Retardation method.
- Calorimetric method.
