Assessing the vibration behaviour of generator stator end-windings - Laborelec, GDF Suez

Generator stator end-windings are submitted in operation to a combination of complex electromagnetic and mechanic forces. These forces recurrently lead to the early ageing of the end-windings through the appearance of white dusting and greasing detected by inspections during overhaul. The vibration behaviour of the end-windings is regularly depicted as one of the main
contributors to the root cause. Based on OROS instruments, Laborelec offers a complete methodology specifically developed for the vibration assessment of generator stator end-windings. This methodology is universal for all machine types and is independent from the generator manufacturer.
