Performance measurements on a Pelton turbine model

, 2010
: Pelton hydraulic turbines are impulse-type turbomachines commonly used in hydro-electric plants with medium-to-high water head and in various energy recovery applications. The aim of the present work is to provide detailed performance measurements on a

The reliability of wind turbines [PDF]

, 2008
The residual scepticism surrounding the installation of wind turbines, is mainly due to the perceived lack of reliability and expense of these energy converters. Because of the commercial significance of reliability, few sources of such data are publicly
