SALIENT POLE GENERATOR FAILURES
This month’s Featured Technical Paper is from the Proceedings of the 2025 International Conference of Doble Clients. The paper is titled: Salient Pole Generator Failures.
Abstract
This paper focuses on failures of a family of salient pole generators from multiple manufacturers ranging from about 15 MVA to about 65 MVA, with nominal operational speeds of 1200 and 1800 RPM. The damage from these failures was considerable, requiring stator core restacking or replacement, stator rewind, and other rotor repairs and/or upgrades. The presentation reviews the basic construction elements of salient pole generators and identifies failure mechanisms and engineered solutions. Long-term maintenance and operational considerations are also discussed.
