Accurate measurement of steam humidity is essential for safe and efficient operation of steam turbines, drawing significant interest from both academic and industrial communities. The primary techniques for measuring steam humidity in steam turbines are systematically reviewed, encompassing thermodynamic, optical, electrical, chemical, and ultrasonic methods. The principles, characteristics, and applicability of each humidity measurement technique are thoroughly examined, and their respective advantages and limitations are critically analyzed. Furthermore, development trends and future research directions in steam humidity measurement technology are explored. The research provides a robust theoretical foundation for selection and optimization of steam humidity measurement techniques.
