Three phase system Adisu Teshale
Introduction • Three phase system, It is also called poly phase system. • Three-phase generators are similar to single phase generator in which the winding is wound in three sets of windings and produce three AC voltages. • Since the three set of windings are placed 120° apart, hence the voltages are three identical sinusoidal voltages 120° apart.
