Abstract

Tank vibration of loaded transformer was measured by 3-axis acceleration sensors to diagnose the abnormal and degraded conditions. Although there have been calculated and reported the natural vibration characteristics of transformer core and windings, the attempts to detect these natural vibrations on the tank were few. These natural vibration characteristics represent the conditions of core and windings. From this point of view, this paper describes what types of tank vibration may occur and how to detect the natural vibrations of core and windings. The measurement data are classified into 3 categories and we can distinguish the difference between small mechanical vibration and other vibration.
