Synchronous generators undergo frequent start-stop cycles due to maintenance or external factors, causing thermal variations that affect stator insulation. This study, conducted at the Balbina hydroelectric plant in Amazonas, Brazil, examines insulation aging trends in stators through partial discharge testing. Results indicate that continuous operation increases the generators’ lifespan.
