본 논문에서는 플린트 유리섬유를 센서소자로 사용하여 새로 개발된 유연성이 뛰어난 광섬유 패러데이 효과 전류 센서에 대한 설계 및 실험 결과를 기술한다. 신형은 플린트 유리섬유 끝에 거울을 코팅해 빛이 그 안에서 왕복 투과되는 방식이다. 왕복 전송에 의해 광섬유 비틀림으로 인한 편광면 회전 효과가 자동으로 취소됩니다. 플린트 유리섬유는 광탄성 상수가 낮고 회전이 자동으로 취소되므로 섬유를 통과한 빛의 편광 상태가 안정적입니다. 따라서 새로운 반사형에서는 정확성을 유지하기 위해 내구성이 뛰어난 원형 프레임으로 플린트 유리섬유를 지지할 필요가 없습니다. 그래서 센서헤드는 작고 가벼우며, 부싯돌 유리섬유를 전류도체에 감아주면 잡아당기거나 절단하지 않고 기존 전력기기에 쉽게 장착할 수 있다. 개발된 센서 모델을 이용하여 안정적인 특성을 검증하기 위한 실험을 진행하였다. 실험에서는 센서의 최종 출력신호와 플린트 유리섬유의 곡선 형태와의 관계를 조사하였다. 실험을 통해 최종 출력은 섬유 곡선의 모양에 거의 완벽하게 독립적이라는 것이 분명해졌습니다. 또한 센서의 정확도가 일본의 전력 시스템 보호를 위한 기존 전류 변환기의 표준을 준수하는 것으로 확인되었습니다.

Abstract: In this paper, design and experimental results are described about a newly developed highly flexible fiber Faraday effect current sensor using the flint glass fiber as the sensor element. In the new type, a mirror is coated at an end of the flint glass fiber, and light takes round trip transmission in it. By the round trip transmission, the effect of rotation of polarization plane due to the torsion of the fiber is automatically canceled. Because of the low photo-elastic constant of the flint glass fiber, and the automatic canceling of the rotation, the polarization state of light passed through the fiber is stable. Therefore, in the new reflection type, it is not necessary to support the flint glass fiber with a durable circular frame to maintain accuracy. And so, the sensor head is small, light, and can be easily installed to existing power apparatus by winding the flint glass fiber around the current conductor without pulling out or cutting it. Experiments were done to verify the stable characteristics using the developed sensor model. In the experiments, relation between the final output signal of the sensor and shape of the curve of the flint glass fiber were examined. From the experiments, it became clear that the final output is almost perfectly independent on shape of the curve of the fiber. It was also confirmed that accuracy of the sensor conform to the standard of conventional current transducers for protection of power systems in Japan.
