Eddy Current Monitoring toward Advanced Plant Maintenance
An approach of plant monitoring by means of eddy currents is proposed to observe the health of plant elements.Our eddy current monitoring(ECM)system performs a couple of tasks; one is to monitor the behavior of cracks found in the in-serve inspection(ISI); the other is to quantitatively evaluate the crack propagation from both the obtained ECM signals and 3D eddy current field analysis.The 3D eddy current field analysis also accomplishes the eddy current focusing technique,resulting in the optimal design of probes for the monitored cracks.The software and hardware simulations demonstrate the ECM signals just corresponding to the crack propagation.A benchmark test reveals that our ECM system gives one of the efficient and reasonable tools for the advanced maintenance.
