Paper Abstract

The ENEL power station of Bargi, Italy, houses a 185 MVA synchronous hydrogenerator/motor. Since three years, the vibrations of the high-voltage stator end-windings are continuously monitored by twelve optical fiber sensor, each consisting of an intensity-modulated proximity-sensor which detects the motion of an elastic cantilever by means of the triangulation technique. The results of vibration measurements over a period of several hours are presented, by considering both the pumping and generating modes of operation.
