Infrared Maintenance Program
John Leedy, P.E.
Preventive/Predictive Maintenance
With Infrared Imaging
What is Infrared Imaging?
• It is a method of detecting radiance or heat of a surface without contact to the object being measured.
• An image or picture is created by combining many radiance measurements and converting them to an intensity value.
• The more radiance or heat the object surface has the brighter it is represented in the image.
What Can Detecting Radiance Or Heat Do For Me?
• Identify restrictions to electrical current flow which cause failures and nuisance tripping. (Most common form of infrared inspection).
• Identify mechanical issues such as bearing wear, improper lubrication and misalignment.
Why Should I Use Infrared?
• Reduce forced maintenance shut-downs.
• Reduce associated production losses.
• Repair components prior to complete failure.
• Reduce required repair time.
• Reduce repair costs.
High Voltage Electrical Inspections
• Failures often cause complete plant shut-down.
• Repairs can be time consuming.
• Many facilities lack repair parts inventory.
• High failure costs.• Failures are usually
less common.

Low Voltage Electrical Inspections
• Failures seldom cause complete plant shut-down.
• Failures are usually more common due to higher loading %.
• Compounded costs over time can be significant.

Mechanical Inspections
• Less common than electrical inspections.
• Cause and effect generally less understood than electrical systems.
• Has definite benefits but is often limited by restricted access.

What Should I Expect In An Infrared Inspection?
• Thorough inspection, good work ethic.
• Good image quality for easier problem identification.
• Trained & experienced technician for both the inspected equipment and infrared imaging.
• Thorough & convenient documentation.
How Expensive Is Infrared Equipment?
• High resolution non-Radiometric or low resolution imagers range from ~$20,000.00 to $35,000.00.
• Radiometric and high resolution imagers range from $35,000.00 to $55,000.00.
How Expensive Are Infrared Inspection Services?
• Usually based on daily rates of $600.00 to $1,000.00 plus expenses.
• Number of days dependent on size of facility, equipment integrity and thoroughness of inspection.
• Frequency of inspection depends on utilization and operating environment.
