ABSTRACT:
Apparatus and method for connecting a generator to an energized bus includes a circuit for determining voltage differential between the generator voltage and the bus voltage; a circuit for connecting the generator to the bus when the voltage differential reaches a predetermined threshold; a circuit for limiting the generator field current during build-up so that the generator reaches a predetermined speed before the generator is connected to the bus.
