Abstract

The majority of electrical drive systems in use are powered by a so-called three-phase (three wire) supply. The main reason for this is that a more efficient energy transfer from supply to the load, such as a three-phase AC machine, is possible in comparison with a single (two wire) AC circuit. The load, being the machine acting as a motor, is formed by three phases. Each phase-winding of which has two terminals, yielding a total of six terminal-bolts, usually configured as sketched in figure 4.1. The phase impedances are assumed to be equal.
