  • Low-cost revamping of the Rothenbrunnen power plant

    Introduction At the Rothenbrunnen powerplant of Kraftwerke Zereraila AG (KWZ) all Pelton runners were replaced between 1999 and 2000, using the solution of FRAVIT's „forged Pelton runners" . Thanks to the successful replacement of the runners, KWZ avoided the high cost of complete refurbishment of the turbines: the new runners fit with the existing turbines, i.e. casing, injector, ...

  • New Italian norms to regulate the non-destructive inspections in the manufacturing and in the maintenance of parts of hydraulic machinery

    Introduction This paper presents two proposals of norms (standards) which have been discussed by a Working Group of UNI (Ente Italiano di UNIficazione, Italian expression of ISO) during 1998-2000, and will be soon submitted to examination by the technical verification commission of UNI. These proposals aim to provide procedures to perform and evaluate inspections on parts of hydraulic machinery ...

  • Development of a self-rechargeable digital water flow meter

    The objective of this paper is to present the feasibility of a self-rechargeable digital water flow meter (SRDFM) system for water pipes using the latest data processing and wireless communication technologies while causing negligible water pressure drop (head loss). The system uses a Pelton turbine generator to power the electronic circuit, which processes and transmits the signals generated by ...

  • 1997 IFAI award devil Canyon hydroelectric power plant, San Bernardino, California

    Constant demands for water and electricity in heavily populated areas in California prompted the Devil Canyon Power Plant project. Constructed from 1969 to 1974, the power plant is located at the San Bernardino Mountains near the mouth of Devil Canyon. With two pipelines carrying water from Silverwood Lake, an elevation drop of almost 1500 ft (460 m) between the lake, and four Pelton wheel ...

  • Hydro power myths Explains why various schemes such as a pool pumps or rain gutters or pumping water to a tank will not work

    Making electricity from falling water can seem like magic, and that’s led to lots of misconceptions. Here, we’ll separate fact from fiction when it comes to what microhydro systems can and cannot do. Residential-scale microhydro-electric systems have the reputation of being the holy grail of home renewableenergy (RE) systems. While they lack some of the hype, magic, and bling of ...

  • No Place Is Too Far

    The remote location of hydropower stations is often a great challenge when major repair work is necessary. The refurbishment of a large generator in the Scottish Highlands shows how Sulzer finds cost-effective service solutions even in places miles from nowhere. Much of the UK hydroelectric capacity was built during the 1950s. These installations have performed extremely well, especially ...
