like agricultural seed storage, in chemical, biomedical, food, and electronic processing, hospitals, museums_x000D_
libraries and generally, in most buildings. Moisture measurement in high voltage engineering for_x000D_
measurements of water content in transformer oil is very important. Currently the industry is relying on various_x000D_
methods of measuring partial discharge (PD) to determine when a transformer needs to be serviced. Most_x000D_
methods only give indications when damages are already done. The measurement of moisture in the winding_x000D_
insulation paper and frame allows the transformer to be serviced before damages happened, this will lead to a_x000D_
more robust power system and considerable savings. Among several techniques such as electrical sensors, fiber_x000D_
optic sensors are capturing more attention due to small size, light weight, susceptible to multifunctional sensing_x000D_
and more importantly their immunity to electromagnetic interference. Fiber Bragg Grating (FBG) based optical_x000D_
sensors have become widely known and popular. FBGs are compact intrinsic sensing elements, which are_x000D_
relatively low cost to produce, easy to multiplex, and applicable to a range of strain and temperature sensing_x000D_
applications. Recently QPS Photonics Inc. has developed a moisture sensor using two types of FBGs, a_x000D_
standard FBG and an advanced phase shifted gratings. This sensor was developed by incrementally applying 10_x000D_
layers of polymide coating over the grating area, and cured at 300 C. The coating upon contact with moisture,_x000D_
absorbs the moisture, slightly expands and recovers from the inherent strain. The objective of this project is to_x000D_
develop a high sensitive and cost effective optical sensor for monitoring the temperature and moisture inside a_x000D_
high voltage power transformer. This project is involved with the design of packaging and characterizing the_x000D_
performance of the sensor which capable to detect small trace of moisture. This would be the first time in the_x000D_
world that such a capability will be developed, allowing transformer owners to understand, in real time, the_x000D_
transport of moisture which depends on the operating oil temperature, and loading., program purpose french : Precise measurement of humidity and moisture has many applications particularly monitoring environments_x000D_
