A study on the computer diagnosis that apply Neural-Fuzzy algorithm accumulation detection of Partial Discharge signal

광섬유 내의 유도 브릴루앙 산란광을 이용한 초고압전력케이블 열화진단에 관한 연구

This study is an application field by using optical fiber. The system to measure sBs from optical fiber is designed, So it can be used as a temperature sensor. by using frequency shift, resulting from temperature changes. the frequency shift is checked by changing temperature from $25^{\circ}C$ to $69^{\circ}C$ with chamber in the laboratory and using 40Km optical fiber. It's also measured by varying the length of optical fiber The program to do the real-time monitoring and analyze the measured data is created to find accurate frequency. It can be used as an optical fiber sensor, which is capable of measuring temperature and distance by using sBs.
