Magnetic amplifier step regulator

PROPER VOLTAGE regulation is now becoming an increasingly important factor in efficient operation of electric power distribution systems. The degree to which a voltage regulator performs its function on these systems depends upon the accuracy and reliability of its controls. Because of fluctuating voltage conditions on most systems, the voltage-regulating and time-delay elements of the controls are subjected to many more operations than the regulator itself. A new control system has been developed employing the unique features of bistable magnetic amplifiers to perform the functions of the voltage regulating and time delay elements.
