Abstract
In this paper, we propose the use of a Cross Recurrence (CR) Plot Analysis based technique applied on signals captured using fiber Bragg grating sensors to improve the accuracy of detection and localization of partial discharges. With the help of detailed simulations, the performance of the proposed technique in estimating the Time Difference of Arrival (TDOA) is evaluated. A novel technique of extracting the frequency from CR plots is also proposed and frequencies of single as well as multiple-tones signals are extracted successfully. Controlled experiments are conducted to verify the technique and the estimates of location are found to be within an error of less than a centimeter. © 2017 IEEE.
