TRANSFORMER STATUS MONITORING USING FIBER SENSING
This abstract first appeared for US patent application 18938281 titled 'TRANSFORMER STATUS MONITORING USING FIBER SENSING
Original Abstract Submitted
Disclosed are systems and methods directed to a frequency analysis approach to transformer status monitoring using distributed fiber optic sensing to monitor a phase delay of a 120 Hz vibrational signal and determining an angular difference between a designated point and a reference point. Operationally, systems and methods according to aspects of the present disclosure identify phase delay patterns of a single transformer from its vibrational humming and combined vibrational signals of multiple transformers.
