Abstract

In view of difficult for the power transformer insulating oil level in the real-time online monitoring of the artificial. Using fiber Bragg grating as the insulating oil level sensor. TMS320F2812 digital signal processor was used as the processing and control core. Analyzed the structural principle of fiber Bragg grating sensor and its demodulation system, introduced the hardware components and software implementation. Experimental results show that the system has high precision measurement, good stability and reliability.
