Sagnac형 광섬유 배열센서를 이용한 유증 음답 탐지 연구

Investigation of the Acoustic Detection in Transformer Oil Using Sagnac Fiber Optic Sensor Array

Fiber optic sensor has bee widely used in the industrial applications. For the application of acoustic detection of the high voltage electric transformer Sagnac interferometer can be used. In this paper several different materials of mandrel were used in the fiber sensor array. Based on the transformer oil fiber optic sensor is more sensitive than in the air.
