Support feet of a generator are mounted on foundation columns spaced laterally one from the other, with one column having a block in a recess for receiving the feet on one side of the generator. Guides on a radius and supported by the generator foundation extend through notches on the underside of the block. To locate an end of the generator displaced horizontally from the turbines, the generator is unloaded from the foundation and the block is removed. The generator is then loaded onto the guides and pivoted about a vertical axis to locate at least one end out of alignment with the axis of the turbines enabling removal of the generator rotor in an axial direction.

A sensor measures temperature in stationary components of electrical machines using fiber optics. An optical fiber is embedded in a non-metallic ribbon. Notches are cut in the ribbon to effect bends that accommodate a shape of a stationary component. The ribbon and optical fiber are attached to the stationary component. A series of laser pulses can be injected from at least one end of the optical fiber, and the stationary component temperature can be monitored by interrogation of reflections from the series of laser pulses.
