Induction voltage regulators are classified into three-phase AC and single-phase types.The structure of a three-phase induction voltage regulator is similar to that of a three-phase wound-rotor induction motor. The key differences are that the rotor’s rotation range in an induction voltage regulator is limited, and its stator and rotor windings are interconnected. The internal wiring diagram of a three-phase induction voltage regulator is shown in Figure 2-28(a), which illustrates only one phase
