(3) Neatness in handwriting and clarity in expression carries weightage. PART – A. Find the no-load terminal voltage of a three-phase, four- pole a.c. generator from the following data. Flux per pole (assumed sinusoidally distributed) = 0.14 webers. Slots per pole per phase = 2. Conductors per slot = 2. Assume a Distribution Factor of 0.966.
