Analysis of shaft voltages in large synchronous generators

In order to improve maintenance of large turbogenerators, a new diagnostic tool is developed by analysing shaft voltages. This study is validated by a comparison between the measurements made on a 30 kVA synchronous machine and its modelling with a finite element program.
