Harmonic Analysis
Harmonic Analysis is a way to check the quality of electrical power in buildings, factories, or power systems. It's like checking the 'health' of electrical systems by measuring unwanted electrical patterns that can cause problems with equipment. Think of it as running a diagnostic test on a car, but for electrical systems. Engineers use this to prevent equipment damage, reduce energy waste, and ensure electrical systems run smoothly. When you see this term on a resume, it usually means the person knows how to identify and fix power quality issues in industrial or commercial settings.

Example Interview Questions
Senior Level Questions
Q: How would you explain the impact of harmonics on a facility's electrical system to a plant manager?
Expected Answer: A senior engineer should be able to explain in simple terms how harmonics can increase energy costs, cause equipment to fail early, and potentially shut down production. They should outline practical solutions and their cost-benefits.
Q: Describe a challenging power quality issue you solved using harmonic analysis.
Expected Answer: Look for answers that demonstrate project leadership, problem-solving process, and ability to implement practical solutions while considering budget constraints and business impact.
Mid Level Questions
Q: What tools and equipment do you use for harmonic analysis?
Expected Answer: Should be familiar with common power quality analyzers and software tools, able to explain how they use these tools to collect and analyze data, and interpret results.
Q: How do you determine if a facility needs harmonic analysis?
Expected Answer: Should mention common signs like equipment overheating, unexpected shutdowns, or high energy bills, and explain the process of initial assessment.
Junior Level Questions
Q: What are the basic steps in performing a harmonic analysis?
Expected Answer: Should be able to describe the basic process: connecting measurement equipment, collecting data, analyzing results, and identifying major issues.
Q: What safety considerations are important when conducting harmonic analysis?
Expected Answer: Should demonstrate understanding of electrical safety basics, proper use of personal protective equipment, and following safety procedures.
