【Abstract】 Acoustical technology has many valuable diagnostic type of applications. Although it is very difficult to apply acoustic techniques to the detection of stator insulation in large generators for its materials and complicate structures, some of these acoustical techniques are successfully utilized. In this paper, these different methods are described and evaluated after a brief introduction of structure andacoustic signatures of stator insulation.更多还原
