Nowadays, the production of optical fiber sensors of electrical current based on the Faraday effect is due to its advantages over other sensors, such as high sensitivity, safety against electromagnetic interference, ability to work in high voltage and high current environments, low energy consumption, and low price. , light weight and small size, electrical insulation, the ability to connect to electronic equipment without breaking the circuit, and a wide frequency bandwidth, etc. have attracted the attention of scientists. Therefore, this type of sensor can be used in many cases, including high power grid systems, plasma current measurement, windmills, lightning current measurement, etc.
In this thesis, the design and construction of optical fiber sensor to measure high currents has been studied in two sections, design and simulation. The performance of this sensor has been investigated for currents up to 195 amps. This sensor operates at a wavelength of 1550 nm and is based on polarimetry using optical fiber as a magneto-optical material. The results of the experiments show that the magnetic field of 7.4 Gauss caused the light polarization to rotate by 0.4542 radian (26.02 degrees), which can be seen on the power meter displ.
