Abstract
Conventional current sensor has several limitation and disadvantage, particularly to work for high power applications. The most notable weakness is against a phenomenon called Electromagnetic Interference (EMI). Therefore, crucial aspect such as accuracy, sensitivity, reliability and safety are greatly affected and the result is unreliable. The advancement of the fiber optic technology in recent years opened up a better solution to this conventional problem. The motivation of this project is to implement and enhance fiber optic as current sensor. In this research, a fiber optic interferometer is applied to receive inputs from a modulator, which resemble the presence of electromagnetic field around a conductor carrying an electrical current. The purpose of this research are to design and demonstrate a fiber optic current sensor using Sagnac interferometric scheme. The design is simulated using Optisystem software. The performance of the fiber optic current sensor was observed and analyzed. Analysis has focused on the output waveform, transmission losses, power consumption, and sensitivity of the device. In terms of stability, Sagnac interferometer with CW mode laser as light source provided the best result. However, configuration with pulse mode laser gave another advantage over CW mode, which are low transmission loss, low power consumption and better sensitivity.
