ČSN EN IEC 60034-2-2 ED.2   (350000) Točivé elektrické stroje - Část 2-2: Specifické metody pro určování dílčích ztrát velkých strojů ze zkoušek - Dodatek k IEC 60034-2-1

Anotace textu normy ČSN EN IEC 60034-2-2 ED.2   (350000)

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 results in a greater uncertainty.

The specific methods described are Calibrated-machine method, Retardation method, Calorimetric method and Summation of losses for permanent magnet excited synchronous machines.
