Claim:
A method of replacing slot armor and slot liners in radial slots of generator rotors, wherein each radial slot has a pair of non-metallic insulating slot armors and a pair of L-shaped metal slot liners therein, comprising: (a) removing a winding from respective radial slots in the generator rotor; (b) removing existing pair of non-metallic insulating slot armors and pair of L-shaped metal slot liners from each of the radial slots in the generator rotor; (c) installing a single pair of L-shaped slot armor components in each radial slot as replacements for said pair of slot armors and pair of slot liners, each L-shaped armor component constructed of a powder-coated metal; and (d) installing a winding in the radial slots, wherein the L-shaped slot armor components are sized to substantially fill any space between the winding and adjacent walls of the radial slots created by the removal of the pair of slot armors and pair of slot liners from each radial slot.
