Pelton Wheel
A Pelton Wheel is a special type of water wheel used in hydroelectric power plants to generate electricity. Think of it like a very sophisticated water wheel with special cups or buckets around its edge that catch fast-moving water to spin the wheel efficiently. It's particularly good for locations where water drops from high places with high pressure, like mountain streams or dams. When someone mentions this in their resume, they're usually talking about experience with hydroelectric equipment, specifically this type of turbine that's common in many power plants. It's named after Lester Pelton, who invented it, and is one of the main ways we convert falling water into electrical power.

Example Interview Questions
Senior Level Questions
Q: How would you handle a situation where a Pelton Wheel system is showing decreased efficiency?
Expected Answer: A senior engineer should discuss inspection procedures, common causes like worn buckets or nozzle problems, and demonstrate knowledge of efficiency calculations and maintenance planning.
Q: What factors do you consider when sizing a Pelton Wheel for a new installation?
Expected Answer: Should explain considerations like water flow rate, available head (height of water drop), power output requirements, and site conditions in simple terms.
Mid Level Questions
Q: What are the main maintenance requirements for a Pelton Wheel system?
Expected Answer: Should describe regular inspection points, common wear patterns, maintenance schedules, and basic troubleshooting procedures.
Q: Explain the safety considerations when working with Pelton Wheel systems.
Expected Answer: Should discuss water pressure safety, equipment lockout procedures, personal protective equipment, and emergency shutdown protocols.
Junior Level Questions
Q: What are the basic components of a Pelton Wheel system?
Expected Answer: Should identify main parts like the wheel, buckets, nozzles, and housing, and explain their basic functions in simple terms.
Q: How does a Pelton Wheel convert water power to electrical power?
Expected Answer: Should explain the basic principle of water hitting the buckets to spin the wheel, which turns a generator to produce electricity.
