Problem Statement
- Existing partial discharge (PD) detection systems based on fluorescent optical fibers have limited sensitivity, particularly for low-magnitude discharges and early detection.
- Need for Enhanced Efficiency and Sensitivity: There is a lack of prior art addressing the enhancement of efficiency and sensitivity in PD detection systems using fluorescent optical fibers.
- Potential Solution: The introduction of a thin layer of 2D materials as a coating on fluorescent fiber optics could potentially improve the efficiency and sensitivity of PD detection systems.
Technology
- The 2D material-based coating significantly enhances the sensitivity of the optical fluorescent fiber sensor for detecting partial discharges (PD), providing more than double the sensitivity compared to uncoated fibers.
- The fabricated sensor demonstrates optical emission spectrum in the UV range, with distinct emission lines at specific wavelengths, allowing precise detection of PD. Additionally, fast Fourier transform analysis reveals clear discharge signals.
- The PD sensor with the 2D material coating shows substantial improvements in partial discharge inception voltage (PDIV), with enhancements of 34.8% for maximum deviation, 30.8% for surface discharge, and 17.7% for discharge due to particle movement, indicating higher efficiency and sensitivity in PD detection.
