Molybdenum disulphide coated Fluorescent fiber for detection of corona discharges in transformer oil

Early detection of corona discharge plays a critical role in avoiding catastrophic failure of transformer insulation. In the present study, we explore the use of two-dimensional (2D) material coated fluorescent fiber for early detection of corona discharge. Specifically, Molybdenum disulphide (MoS 2...

Description
Summary:Early detection of corona discharge plays a critical role in avoiding catastrophic failure of transformer insulation. In the present study, we explore the use of two-dimensional (2D) material coated fluorescent fiber for early detection of corona discharge. Specifically, Molybdenum disulphide (MoS 2 ) material is dip coated over a commercial grade fluorescent fiber. The band gap of the coated MoS 2 material is found to correspond to the visible and ultra-violet (UV) spectral regions. Corona inception voltage (CIV) detection adopting MoS 2 coated fluorescent fiber exhibits detection efficiency with the percentage difference of 32% in comparison to the UHF technique. Also, fiber coating enhances the energy content of the discharge signal by the difference of 150% with the uncoated fluorescent fiber. The phase resolved partial discharge (PRPD) studies reveal that the discharge is observed at the peak of the applied AC voltage.
