Abstract
The concept of partial discharge (PD) detection using acoustic methods, for the use in high voltage cable systems, is being developed. A photonic acoustic sensor based on a fibre Bragg grating (FBG) has been shown to detect acoustic emission from PDs. The sensitivity of a generic FBG appears insufficient for practical applications. An improved FBG photonic acoustic sensor has been developed which exhibits a 50-60 dB gain in sensitivity when compared with a generic FBG. This article describes the design process and test results of the improved FBG-based PD photonic acoustic sensor.
