Abstract :
This paper describes the parameters required for a thermoset hydro-generator stator winding to achieve a service life of 50 years. Such parameters covering design, manufacture, installation, online monitoring and maintenance functions have been found to be relevant based on 36 years of design and operation experience. The database includes North American, European and Far Eastern hydro generators up to 20.5 kV-500 MVA. Parameters covered can be simply stated as design, installation and manufacture: the DIM rule
