Thermal Imaging

Term from Electrical Repair industry explained for recruiters

Thermal imaging is a tool and technique that helps technicians see heat patterns that aren't visible to the naked eye. It uses special cameras that show hot and cold spots in different colors, making it easier to find problems in electrical systems, insulation, or machinery. Think of it like taking a temperature picture of equipment or buildings. Repair technicians use this technology to spot potential issues before they become major problems, like overheating electrical components or energy leaks in buildings. Other names for this technology include infrared imaging, infrared thermography, or heat mapping.

Example Interview Questions

Senior Level Questions

Q: How would you develop a preventive maintenance program using thermal imaging?

Expected Answer: A senior technician should explain how to create inspection schedules, set temperature thresholds for different equipment, train team members, and establish documentation procedures for findings and follow-ups.

Q: What factors can affect thermal imaging readings and how do you account for them?

Expected Answer: Should discuss environmental conditions like ambient temperature, reflective surfaces, distance from target, and explain how to adjust camera settings and analysis techniques to compensate for these factors.

Mid Level Questions

Q: How do you interpret different color patterns in thermal images?

Expected Answer: Should explain how to read temperature variations shown in different colors, identify normal vs. abnormal patterns, and demonstrate understanding of what various patterns typically indicate in electrical or mechanical systems.

Q: What safety procedures do you follow when conducting thermal imaging inspections?

Expected Answer: Should describe proper personal protective equipment, safe distances from live electrical equipment, and proper procedures for working in different environments.

Junior Level Questions

Q: What are the basic components of a thermal imaging camera?

Expected Answer: Should be able to identify main parts like the lens, display screen, temperature sensors, and basic controls, and explain their basic functions.

Q: How do you prepare equipment and areas for thermal imaging inspection?

Expected Answer: Should explain basic preparation steps like ensuring equipment is running under normal load, removing obstacles, and checking environmental conditions.
