Abstract
A temperature probe for use in oil-filled transformers comprises an optical fiber, a temperature sensitive member, and a protective cylindrical sheath. The optical fiber and the sensitive member are located in the protective sheath, and continuous longitudinal slit is defined along the length of the sheath to allow oil to flow therein. The optical fiber is mounted in and to the sheath using a bonding material and at a distance from the sheath. The sensitive member is adhesively mounted to the optical fiber, within the sheath, and at a distance thereof.
