Abstract
Brillouin optical correlation domain analysis (BOCDA) offers high spatial resolution and multi-point measurement capabilities which are ideal for transformer winding temperature measurements. In this article, a BOCDA prototype is developed by changing many equipment to modules, and using field-programmable gate arrays (FPGA) for the control, acquisition, and processing. The system achieves a desired performance with a spatial resolution of 10 cm, a Brillouin frequency shift (BFS) accuracy of about 0.9 MHz, and a measurement speed of 500 points/second.
