Towards winding deformation assessment from vibration signals using an optical sensor
IET Science, Measurement &Technology, Volume 19, Issue 1, January/December 2025.We report on the feasibility of monitoring mechanical integrity of transformer winding from the vibro‐acoustic signals using an FBG sensor. The investigations were performed using a specifically designed one column winding transformer that allows countless non‐destructive deformations.
