Net Head
Net Head is a fundamental measurement in hydroelectric power plants that shows how effectively water can be used to generate electricity. It represents the actual height difference between where water enters the power plant system and where it exits, after accounting for any energy losses. Think of it like measuring the useful height of a waterfall - the higher the net head, the more potential the water has to generate power. When you see this term in resumes, it usually indicates experience with calculating, optimizing, or managing water flow systems in hydroelectric facilities.

Example Interview Questions
Senior Level Questions
Q: How would you optimize net head in a hydroelectric facility?
Expected Answer: A senior engineer should discuss methods like minimizing friction losses, regular maintenance of water passages, optimizing intake designs, and implementing modern monitoring systems. They should mention experience with cost-benefit analysis of different optimization strategies.
Q: What factors do you consider when evaluating net head efficiency?
Expected Answer: Should explain water flow rates, seasonal variations, equipment condition, and environmental factors in simple terms. Should demonstrate experience with long-term planning and problem-solving.
Mid Level Questions
Q: How do you measure and monitor net head in daily operations?
Expected Answer: Should describe basic measurement techniques, monitoring equipment, and regular reporting procedures. Should show understanding of normal operating ranges and when to flag issues.
Q: What maintenance procedures affect net head performance?
Expected Answer: Should discuss routine inspections, cleaning procedures, and basic troubleshooting of water flow systems. Should demonstrate knowledge of preventive maintenance.
Junior Level Questions
Q: Can you explain what net head is and why it's important?
Expected Answer: Should be able to explain net head in simple terms as the useful height of water flow, and its basic importance in power generation. Should understand basic safety procedures.
Q: What basic calculations are involved in determining net head?
Expected Answer: Should demonstrate understanding of simple height measurements, basic pressure readings, and awareness of standard measurement units and tools used.
