Abstract

The chapter delves into the types of partial discharges (PDs) in synchronous generators, highlighting the characteristics and causes of PDs such as corona, delamination, and slot discharges. It explores various methods for measuring PDs, including online and offline techniques, and discusses the challenges and solutions for effective PD monitoring. The text also presents real-world case studies from hydroelectric power plants, demonstrating the application of PD measurements in predictive maintenance and the correlation between PD activity and operational parameters like power, vibration, and temperature. These case studies provide valuable insights into the practical aspects of PD monitoring and its role in ensuring the reliability and longevity of electrical equipment.
