Abstract : The note comprises a short study of the vibration response of two 200 KW no-break power units located at the Naval Communication Station, Stockton, California. Mechanical and structural deficiencies of both units have caused continuous difficulties since their installation. Excessive vibrations were believed to be the main cause of these problems. A preliminary investigation indicated that a number of mechanical alterations and balancing of rotating components would improve the situation. Most of this work has now been completed. Final tests and vibration measurements were conducted and have resulted in a set of spectra which described the vibration response of the no-break power units. Examination of the measurements revealed that both units presently operate within tolerable vibration limits. (Author)
