| Outline of Final Research Achievements |
The main purpose of this reserach is that by studying interaction between discharge and materials, we will create the nanocomposite enameled wires with superior partial discharge resistance that come into practical use as next-generation magnet wires. In the experiments, we have investigated partial discharge phenomenon that occurs across the gap by measuring the electric field strength and also the partial discharge inception voltage (PDIV) determined by surrounding environment factors such as humidity and air pressure when an impulse voltage is applied to a twisted-pair sample imitating coil windings. The life of a nanocomposite enameled wire depends on a good dispersion state of nano-filler that provides effective surge resistance. We have investigated the dispersion state as a fuction of the filling rate by using the world's largest synchrotron radiation facility (Spring-8) and found the optimum filling rate.
