Abstract
A manual/automatic synchronizing circuit is detailed that uses triply redundant protective levels for both the manual and automatic circuits. The first and second protective levels, shared by both circuits, comprise a solid-state automatic synchronizing relay in tandem with a solid-state synchronization check relay. An operator/synchroscope provides the third protective level for the manual circuit, while a microprocessor based governor provides the third protective level for the automatic circuit. A review is presented of the philosophy, design, and operation of the circuit.<>
