| Outline of Final Research Achievements |
The purpose of this study is to propose the innovative development method for power apparatus that brings the best diagnostics method and consequently contributes to construct the smart power system with highly reliability without faults and accidents in the system. We investigated the discharge current waveforms for the typical insulation media, especially for the power cable solid insulator, with the super high frequency wideband measurement system we have developed and extracted the feature values in view of the diagnostics. According to the FDTD analysis for propagation properties of discharge-emitted electromagnetic waves based on the measured current waveforms, it was achieved that optimal sensor specification and sensor arrangement in the apparatus were shown by the calculation. This result suggests that we can propose the new methodology to develop the innovative diagnostic system for the power apparatus and exhibit it.
