Distributed Fiber Sensing and Dynamic Ratings of Power Cable

The book starts with an introduction to DTS, its functioning and possible applications. This is followed by a description of the available fiber optic cables, their construction, installation methods and testing. Various testing methods are discussed and the advantages and disadvantages of each are given. The next topic is a discussion of the application of the DTS systems in a utility environment. In particular, possible placement of the fiber optic cable is described and the advantages of each method of installation are elaborated on. A full chapter is devoted to the explanation of the cable ampacity (current rating) calculations and how the measured fiber temperature is used to obtain the dynamic cable rating information in real time. A brief description of the leading RTTR suppliers, including verification methods they used before introducing their products to the market is offered. Finally, future applications of the DTS technology in other aspects of power system operation are discussed.
