In this paper we present the results of fundamental study to introduce the in-place fast Haar wavelet transform to vibration diagnosis for a turbine and a generator. It is required to detect typical vibration of the turbine and the generator accurately. Modern power plants usually use one-high pressure and one or two lower pressure turbines. We made the turbine model with 3 rotors supported with journal bearings to simulate rotor-to-stator contact. The contact vibration was measured with displacement meters, acoustic emission sensors and accelerometers. The acceleration signals accompanied by the contact were visualized in the time-frequency domain by the in-place fast Haar wavelet transform. The in-place fast Haar wavelet transform can clearly detect the components accompanied by the contact
