Abstract: (471 Views)
In this research, a distributed partial discharge detection system based on optical fiber sensing, and employing Apodized π-Phase Shifted Fiber Bragg Grating (FBG) sensors is proposed and analyzed, in order to detect power transformer oil breakdown. It is shown that applying phase shift on FBG can extremely enhance its sensitivity. In addition, by applying a Gaussian apodizaion on the FBG, we obtain almost 100% sidelobe suppression in its spectrum, which not merely does result in accurate detection but also gives us another degree of freedom to manipulate the line width of the sensor to the desired value.
