Systems such as slide gates, the water level, the emergency release and the dam wall load must be controlled and monitored remotely for hydroelectric plants. Fiber optic systems are perfect for this purpose. Fiber optics are ideal for monitoring systems over large distances. From a central station control point, the cables are installed to sub-control points and then further to various smart electronic devices. HUBER+SUHNER supplies smart cabling solutions which significantly facilitate the installation of a communication network including fieldbus and enable data to be transmitted reliably in harsh environmental conditions.
