Abstract
A system is provided. The system includes a fiber optic current sensor, and a fiber optic current transducer optically coupled to the fiber optic current sensor and configured to receive polarized light from the fiber optic current sensor, generate an electrical signal from the polarized light, and isolate a direct current (DC) component of the electrical signal. The system further includes a monitoring circuit communicatively coupled to the fiber optic current transducer and configured to receive the DC component from the fiber optic current transducer, and generate an output signal based on the DC component, wherein the output signal is indicative of an operational state of the fiber optic current sensor and the fiber optic current transducer.
