ABSTRACT:
A line synchronous generator with an exciter and generator stage. The exciter stage includes an exciter stator and an exciter rotor, and the generator stage includes a generator stator and generator rotor. In one embodiment, the stators are wound with primary windings for connection to an AC power source and the rotors are wound with secondary windings. In an alternative embodiment, the rotors are wound with primary windings for connection to the AC power source and the stators are wound with secondary windings. The proper phase angle alignment of the secondary windings are determined by connecting the primary windings of the exciter and generator stages to the AC power source, and connecting the a secondary winding of the exciter stage to a secondary winding of the generator stage. The remaining open secondary leads are then tested for two pairs having a voltage equal to two times the line voltage, and two pairs having a voltage equal to .sqroot.3 times the line voltage. The two pairs of open secondary leads having a voltage equal to two times the line voltage are connected together.
