A Kaplan Turbine is a special type of water wheel used in hydroelectric power plants to generate electricity. Think of it as a propeller-like device that efficiently converts flowing water into power, particularly useful in places with varying water flow rates. It's different from other water turbines because its blades can be adjusted to match changing water conditions, similar to how airplane propellers can be adjusted. When you see this term in resumes, it usually indicates experience with hydroelectric power generation equipment. This technology is commonly mentioned alongside other hydropower systems like Francis turbines or Pelton wheels.
