What is BS EN 62256-Hydraulic turbines?
The purpose of BS EN 62256 is to assist in identifying, evaluating, and executing rehabilitation and performance improvement projects for hydraulic turbines, storage pumps and pump-turbines.
BS EN 62256 covers turbines, storage pumps and pump-turbines of all sizes and of the following types:
- Francis
- Kaplan
- Propeller
- Pelton (turbines only)
- Bulb turbines
BS EN 62256 also identifies without detailed discussion, other powerhouse equipment that could affect or be affected by a turbine, storage pump, or pump-turbine rehabilitation.
Who is BS EN 62256-Hydraulic turbines for?
BS EN 62256 on hydraulic turbines, storage pumps and pump turbines is useful to:
- Hydraulic turbines, storage pumps, and pump-turbines owners
- Hydraulic turbines, storage pumps, and pump-turbines consultants
- Hydraulic turbines, storage pumps, and pump-turbines suppliers
- Hydraulic turbines manufacturers
- Storage pumps and pump-turbine manufacturers
