Thermographic techniques have for years been used to locate minor interlaminar faults in the stator cores of steam turbine-driven generators. The technique has been largely employed in a quality control or routine maintenance function. However similar thermo-graphic techniques can be used to detect interlaminar faults and monitor repairs of an extensively damaged stator core of a large hydroelectric generator.
