Abstract :
In order to estimate the remaining life of a hydro power plant generator bars in Iran, one new and four old stator bars of the generator are tested under combined electrical, thermal and mechanical aging stresses. Partial discharge quantity (total integrated charge of the bars in cooling-down period) before and during the aging is used for the life assessment.
