摘要：

A multi-point fibre optic temperature sensor network integrated inside a power transformer for continuous monitoring hot-spots on windings, cellulose insulations and oil, is demonstrated and tested. The temperature sensors are based proprietary encapsulated fibre Bragg grating (FBG) sensors and the optical interrogation unit uses a special design( narrowband high power broadband fibre source. The fibre optic sensing network is integrated into a 440 MVA pow transformer having 12 temperature sensing points, distributed over several physical locations inside de transform (windings, cellulose insulators, magnetic circuit and cooling oil entrance and exit).
