Abstract
A Wye ring system for a rotor of a generator includes a replacement Wye ring configured to replace an existing Wye ring serving as a floating neutral connection in the rotor. The replacement Wye ring is positioned radially inside the existing Wye ring and co-axial with the rotor. A fastening system is configured for mechanically and electrically connecting the replacement Wye ring to a plurality of connection lugs. The plurality of connection lugs are electrically connected to the rotor windings. The replacement Wye ring replaces the floating neutral connection of the existing Wye ring.
