Abstract
Optical fiber sensor is a subject which has been attracted considerable attention in recent year. Especially, it is being developed for the detection and location of partial discharge in oil-filled transformers. In this paper, we propose and experimentally demonstrate directivity and sensitivity of a hollow cylindrical mandrel sensor. The sound source is a PZT actuator of hollow cylinder type. Several layers of the fiber laminated around the mandrel surface and experiments were performed on three axis modes. The experimental results can be applied to analyze detected signals optimally.
