Abstract
A load dump circuit for a wye connected electric generating machine includes a silicon controlled rectifier connected between the common terminal of the wye and one of the output terminals of the machine. A Zener diode sensing circuit is connected to the common wye terminal and to the control terminal of the controlled rectifier for rendering the controlled rectifier conductive to shunt the output windings in the event of an excessive voltage being developed thereacross as a result of a rapid load reduction or similar condition. Means are also provided to terminate field excitation during the shunting condition.
