SYSTEMS AND METHODS FOR MONITORING FIBER OPTIC CURRENT SENSING SYSTEMS

摘要

A system includes a light source configured to generate a source of light, a fiber optic current sensor (FOCS) configured to detect the source of light, and a decoding circuitry communicatively coupled to the FOCS. The system also includes a health monitoring circuitry communicatively coupled to the decoding circuitry. The health monitoring circuitry is configured to receive a first electrical characteristic component of the first signal and a corresponding second electrical characteristic component of the second signal, to generate a summation of the first electrical characteristic component of first signal and the second electrical characteristic component of the second signal, and to generate an output signal based at least in part on the summation of the first electrical characteristic component and the second electrical characteristic component. The output signal includes an indication of an operational condition of the light source.
