A Francis Turbine is a key piece of equipment used in hydroelectric power plants to generate electricity from flowing water. Think of it like a sophisticated water wheel that turns water movement into electrical power. It's one of the most common types of water turbines used worldwide, especially in medium to large hydroelectric facilities. When you see this term in a resume, it usually indicates the candidate has experience with hydropower generation equipment. It's similar to other water turbines like Kaplan or Pelton turbines, but Francis turbines are particularly valued because they work well in many different conditions and are highly efficient.
