Abstract – In this paper an extrinsic Fabry-Perot based optical fiber sensor for partial discharge detection is reported. The diaphragm of sensor is fabricated using polytetrafluoroethylene. Due to the lower Young’s modulus of the polytetrafluoroethylene in comparison with the silica, polytetrafluoroethylene-based diaphragm has high sensitivity for ultrasound detection caused by partial discharge. The sensor head is a Fabry-Perot cavity including polytetrafluoroethylene-based diaphragm coated with nano silver particles and is placed in one end facet of a single fiber. The results show that the polytetrafluoroethylene based sensor has a sensitivity of ~ 5.4 [μm/kPa] which is ~100 times higher than the silica-based sensor.

Keywords: Partial discharge, polytetrafluoroethylene, Fabry-perot (FP) interferometry, Single mode fiber.
