A reference Pelton turbine design
IOP Conference Series: Earth and Environmental Science, 2012 The designs of hydraulic turbines are usually close kept corporation secrets. Therefore, the possibility of innovation and co-operation between different academic institutions regarding a specific turbine geometry is difficult. A Ph.D.-project at the Waterpower Laboratory, NTNU, aim to design several model Pelton turbines where all measurements ...

Failure investigation of a Pelton turbine runner [PDF]
Engineering Failure Analysis, 2017 In this paper, an uncommon failure of a Pelton turbine has been analyzed. After the monitoring system detected a sudden increase in the vibration levels, the turbine was inspected. The inspection showed that a fragment of one bucket broke off during operation.

Transient Analysis of Pelton Turbine Prototypes
IOP Conference Series: Earth and Environmental Science, 2021 Abstract One of the most critical operating conditions in hydraulic turbines is the start-up transient. This may be characterized by the presence of several resonances, which increase the vibration and stress levels on the runners. At present, its study is of interest due to the more frequent starts and stops of the turbines in the last ...
