Abstract :
The reliability of electro-hydraulic-controlled (EHC) turbine generators can be increased by properly maintaining the hydraulic system and fluid. With increasing cost of production downtime and energy, the demand for reliable turbine generator operation becomes more prevalent year after year. The author describes the necessary requirements for maintaining the electrohydraulic system through proper care of the phosphate ester fluid. In addition, the author addresses the expected results of operating a system with contaminated fluid and the cleanup of a contaminated system
