本研究目的使用智慧型半導體光纖溫度感測器用於油浸式變壓器內部溫度之量測以利其維護，延長變電設備使用壽命及資產管理。研究發現變壓器製造過程或安裝不良導致變壓器的壽命降低及重大事故發生，造成用戶端無電可用之情形。當預先偵測變壓器溫度異常上升時，工程師可提早因應對策，降低停電情形發生。
本研究探討光電式溫度感測技術，利用半導體元件的特性結合光纖技術感測溫度變壓器內部溫度，該裝置包括一個輻射能量源、輻射能導向裝置、裝置在輻射能導向的半導體傳感測元件裝置和一個檢測器。檢測器用於檢測由所述半導體感測元件發射的輻射強度。輻射能傳輸裝置可以使用光纖用於引導輻射能量到半導體和發射輻射能返回到檢測器。半導體檢測元件由合適的半導體材料製成，如砷化鎵，半導體材料可被製造成一個反射鏡或反射稜鏡作為感測元件，及輻射能傳輸裝置的光學元件的一部分。
使用智慧型光纖測溫與傳統式PT100測溫兩種最大差異性有下列兩點：第一點在於反應時間，智慧型光纖測溫探頭埋設在變壓器線圈內，可立即量測變壓器內部線圈的溫度，然而PT100感測元件是模擬出來的線圈溫度，反應速度需較長時間才能顯示內部線圈溫度；第二點為量測方式，智慧型光纖測溫是直接接觸型，能夠即時、準確量測到變壓器內線圈溫度，比傳統式間接測量方式，所讀取的數據更有參考意義。

The purpose of this study semiconductor optic fiber temperature sensors for smart amount of oil-immersed transformer internal temperature measured in order to facilitate their maintenance and prolong the life of substation equipment, and asset management. The study found poorly installed transformer manufacturing process or lead to reduced life of the transformer and a major accident, causing the client no case of electricity available. When the transformer previously detected abnormal temperature rises, the engineer early response measures to reduce outage happens.
This study investigated the photoelectric temperature sensing technology, combined with the use of the characteristics of the semiconductor element fiber temperature sensing technology transformer internal temperature, the apparatus includes a source of radiant energy, radiant energy guiding device, device-oriented semiconductor radiation sensing device measuring element and a detector. A detector for detecting the intensity of radiation sensed by said semiconductor emission element. Radiant energy transmission device may use an optical fiber for directing radiant energy to the semiconductor and emitting return radiation to the detector. Semiconductor detection element made of a suitable semiconductor material, such as gallium arsenide, a semiconductor material can be manufactured as a mirror or reflective Prism as the sensing element, and an optical element portion of the radiant energy transmission means.
In use the intelligent optic fiber of temperature measurement and the PT100 temperature difference between two the largest following two points: the first is that the reaction time, intelligent optic fiber temperature probe is embedded in the transformer winding, can immediately measure the temperature inside the transformer full oil However the PT100 sensing element is a simulated winding temperature, the reaction rate will take longer time to show the internal winding temperature; the second measurement mode, the intelligent optical fiber temperature measurement is direct contact, can instantly and accurately measured volume the transformer winding temperature than traditional indirect measurement, the data read more reference value.
