    Abstract: A disclosed terminal block assembly for a generator includes a terminal block with a base with first and second transverse terminal surfaces adjoining one another. One of the terminal surfaces includes an increased width greater than a length of a cable terminal lug for providing a lightning strike and creepage barrier. The terminal surfaces include spaced apart protrusions extending from the first and second surfaces to provide spaced apart terminal areas overlapping the first and second surfaces. First and second terminal studs are disposed within each corresponding first and second terminal areas and are electrically connected by a bus bar.

    Abstract: A power supply system includes a first saturable reactor electrically connected to a first AC phase input, to a second AC phase input, and to a third AC phase input. The first saturable reactor is electrically connected to a first DC output. A second saturable reactor is electrically connected in parallel with the first saturable reactor to the first AC phase input, to the second AC phase input, and to the third AC phase input. The second saturable reactor is electrically connected to a second DC output. A reactor controller can be operatively connected to the first saturable reactor and to the second saturable reactor to regulate DC output voltage to the first and second DC outputs.

    Abstract: A main field connection to connect to a main field winding has a semi-cylindrical portion with an axially thicker outer surface, an axially thinner inner surface, with an aperture. An extending portion extends from the semi-cylindrical portion to a remote extending end. The remote extending end extends for a first axial distance. The axially thicker portion of the semi-cylindrical portion extends for a second axial distance. A ratio of the first axial distance to the second axial distance is between 0.65 and 1.4. A rotating assembly, a generator and a method are also disclosed.
