1. Method for controlling connection of a generator to an energized bus independent of the use of a direct generator speed sense function, comprising the steps of:

  • a. detecting a voltage differential between the generator voltage and the bus voltage;

    b. connecting the generator to the bus when the detected voltage differential reduces to a selected threshold; and

    c. limiting generator field current during generator build-up prior to connecting the generator to the bus to delay the voltage differential reducing to said threshold so that the generator attains a desired speed before being connected to the bus.
