Abstract
Pengukuran arus listrik menjadi aspek penting dalam menjaga kualitas arus listrik. Dengan berkembangnya teknologi perangkat listrik, diperlukan teknologi pengukuran arus listrik baru yang memiliki sensitivitas dan resolusi yang tinggi. Pada tugas akhir ini telah dirancang dan dibuat sensor arus berbasis serat optik SMS dengan ferofluid untuk pengukuran arus AC. Sensor serat optik ini mamanfaatkan perubahan indeks bias dari Ferrofluid. Ferrofluid merupakan cairan yang terdiri dari campuran nanopartikel Fe3O4 dan surfactant (asam oleat, asam sitrat, dll). Perubahan indeks bias dari Ferrofluid disebabkan adanya medan magnet yang mempangaruhi Ferrofluid. Pengujian dilakukan dengan mengukur perubahan daya pada serat optik SMS yang telah dibungkus oleh ferrofluid dengan Optical Power Meter akibat adanya arus yang mengalir pada kawat penghantar. Rentang arus AC yang digunakan adalah 0-10A. Berdasarkan hasil eksperimen, diperoleh sensitivitas tertinggi sensor arus serat optik SMS sebesar 3.049dB/A. Sensor memiliki tingkat presisi 95% dan resolusi 0.037A. ========================================================================== Electric current measurement become important aspect in electric current quality monitoring. In development of electric trechnologies, electrical system need new current measurment technology with
high sensitivity and resolution. In this study, an
optical fiber current sensor has been developed using SMS fiber structure and ferrofluid for alternating current measurement.
This oprical fiber current sensor works with the change of refractive index of ferrofluid. Ferrofluid is colloidal suspension that was made from Fe3O4 nanoparticle and surfactant(oleic acid, citric acid, etc). The refractive index of ferrofluid will change due to the magnetic field that affect ferrofluid.The experiment was done by me
asuring the change output power of optical fiber
current sensor using Optical Power Meter due to current flow in the wire. The alternating current range used in this study is 0-10A. The result is the SMS fiber current sensor has sensitiviy of 3.049dB/A in the range 2-7A, precision rate 95% and resolution 0.037A.
