D.C. generators are normally designed for maximum efficiency around full-load.
Answer : Generators for peak load plants are usually designed for maximum efficiency at 50 to 75 percent full load.
Answer : The condition for maximum efficiency for a D.C. generator is variable losses equal to constant losses.
Answer : The efficiency of a properly designed synchronous motor will usually fall in range 85 to 95%.
Description : For a transformer, operating at constant load current, maximum efficiency will occur at?
Answer : For a transformer, operating at constant load current, maximum efficiency will occur at unity power factor.
Answer : If equalising bar is connected to the 2 DC generators the current will be equal in 2 generators irrespective of parallel connection so that we connect equaliser bar
