ABSTRACT:
Disclosed is a voltage regulation-unbalanced voltage compensation control connected intermediate the supply and load of the polyphase system, the control including separately adjustable variable impedance elements provided by saturable core reactors for independently varying the voltage drops between the supply and load terminals for each phase. The independent adjustment of the variable impedance elements is effected by a feedback control network varying the magnitude of current supplied to the DC control winding of each saturable core reactor in response to the existing load voltages across the load terminals.
