WebQuestion: From the following test results, determine the voltage regulation by EMF method of a 2000 V, 1 phase alternator delivering a current of 100 A at (a) unity pf, (b) 0.8 leading pf, and (c) 0.71 lagging pf. Test results: full load current of 100 A is produced on short circuit by a field excitation of 2.5 A. An emf of 500 V is produced on open circuit by the WebOct 12, 2024 · EMF equation of alternator By Abragam Siyon Sing Updated on October 12, 2024 The emf induced by the alternator or synchronous generator is three-phase alternating in nature. Let us derive the mathematical equation of emf induced in the alternator. Let, Z = number of conductors in series per phase. WebJul 17, 2016 · K p K d πfN ph Ø. Where K p = Pitch factor. K d = Winding Distribution Factor. f =Frequency. N ph = Number of turns per phase. Ø =Flux. A chording angle of 30° is most useful in an Alternator as it gives the following pitch factors, 0.966 for fundamental, 0.707 for 3 rd harmonic, 0.259 for 5 th and 7 th harmonics and 0.7.7 for 9 th harmonics..
