Optical fiber feeds integrated measurement systems ~for power networks\

The integration of power network measurement systems based on optical fibers used as sensors is now possible, and computers play an important role in this integration. These systems rely on some physical properties of optical fibers and on sophisticated data analysis. They have the advantage of electrical noise immunity and are highly reliable. Here, the authors describe a new generation of measurement systems which makes use of remote fiber-optic sensors, centralized control computers and expert systems.
