New theorical modeling for diagnosis of power cable using optic fiber

광화이버를 이용한 전력케이블 진단을 위한 새로운 이론적 모델링

This paper proposes the strain-insensitive temperature sensing in quasi-distributed sensor system using different thermal expension coefficient materials. This system has the high sensitivity and hasn't the necessity of reference signal. We can monitor the condition of the power cable with this system.
