description: The given work is devoted to the analysis of the circuit of a fiber-optic current sensor, in particular, to the study of the characteristics of an electro-optical modulator and the assessment of their impact on the performance of a fiber-optic current sensor. For this purpose, an experiment was conducted to study the influence of temperature on the operation of an electro-optical modulator and the output characteristics of a fiber-optic current sensor, during which the dependence of the ellipticity of the polarization state on the temperature of the modulator was measured at the output of the optical elements. It was noticed that when the modulator was heated in the composition of the bat-tery, the error in the current amplitude increased up to 0.8 %, while it should not exceed 0.2 %. In this paper, a symbolic simulation of a fiber-optic current sensor is performed using the Jones matrix formalism, and the influence of the tempera-ture of the electro-optical modulator is taken into account in the simulation of the FOCS. It was found that when the temperature of the modulator changes by 0.75 ï°Ð¡, the contrast of the interference signal decreases by 6.3 %, but this dependence is periodic. The results of these studies can be used to further study the temperature dependences of the sensor. Field of application of the results: energy.
