Operating Characteristics of Synchronous Machine

Operating Characteristics of Synchronous Machine: The Operating Characteristics of Synchronous Machine are examined here under conditions of variable load and variable excitation. One of these quantities will be assumed to be held constant at a time while the other will be allowed to vary over a wide range. Further, here too the armature resistance will […]

Rotating Electrical Machines Losses and Efficiency

Rotating Electrical Machines Losses and Efficiency Classification: Rotating Machines Losses Classification – The Losses and Efficiency of a transformer have been studied in earlier lesson. As in the case of transformers, it is more accurate to determine the Rotating Electrical Machines Losses and Efficiency rather than by the direct load test in which the input […]
