A unique diagnostic technology for electric devices has been developed to detect anomaly and estimate the cause of failure of the device easily by analyzing the higher harmonics of electric source current. Higher harmonic diagnosis devices have been realized and improved to be served as the portable device for maintenance works of various electric equipment such as AC/DC motors, inverters, transformers, cables, etc. The higher harmonic technique has been expanded as the online cabled system so that it can s...
