An aircraft differential-voltage cutout

Experience obtained with present multiengine aircraft electrical systems indicates a need for preventing interchange of current between generators when the system is operating at light loads. Such current interchange causes reverse-current cutouts of conventional design to connect and disconnect their respective generators to the system so rapidly that the action is called “chatter.” Conventional cutouts connect the generator to the system when the generator voltage is above a pre-set value. The differential-voltage reverse-current cutout connects the generator to the system when the generator voltage is a pre-set value above the system voltage. A description is given on the design, operation, and advantages of a differentialvoltage reverse-current cutout which prevents interchange of current between the generators.
