A Novel Method for Mechanical Fault Diagnosis of Underwater Pump Motors Based on Power Flow Theory

Due to difficulty in disposing of unsteady and nonlinear acoustic signals by conventional signal process methods, it remains a challenge to develop the noncontacting-based fault diagnosis techniques for underwater pump systems. Fortunately, the power flow theory (PFT), which has been proposed to ana...
