Abstract
SiO2 cladding YAG:Yb crystal core fiber fabricated by the modified rod-in-tube method was demonstrated as a remote sensor for partial discharge faults (PD). The spectra of the crystal fiber and PD fault standard source were measured. When the applied voltage of the PD source is 36 kV, the detection pulse intensity of the sensor decays exponentially with the change of the distance from the PD source to the sensing probe (SSD). Its decay trend in the range of 0-25 cm conforms to the Beer-Lambert law. When the fixed SSD is 7 cm and the applied voltage range of the PD source varies from 35 to 39 kV, the pulse frequency detected by the sensor has a good linear relationship with the applied voltage (R2 = 0.99279). The experimental results indicate that the crystal optical fiber sensor can realize the remote sensing of PD monitoring.
