Acoustic Emission-Based Measurement and Weak Fault Identification of Hydro-Turbine Runners Using a CNN-GRU Framework

Early identification of weak faults in hydro-turbine runners is essential for safe and stable operation under complex hydraulic conditions. Conventional monitoring signals are often insufficient for detecting incipient faults such as runner cracks due to their weak and easily masked characteristics. In this study, an a...
