Cover Story: This study evaluates the use of motor current signature analysis (MCSA) to monitor axial fan motors in highway tunnels under real operating conditions. Measurements were taken remotely from electrical cabins using a permanently installed acquisition system with Rogowski sensors, enabling monitoring of all motors in each tunnel. Harmonics associated with rotor bar defects and eccentricity were tracked over time. Comparison of the results with maintenance reports confirmed eccentricity in two motors caused by bearing defects, while aluminium porosity was suspected in one motor. Furthermore, it is envisaged that machine-learning methods could be applied to the measured signals, together with additional inputs, to enable future remaining useful life estimation and predictive maintenance.
