3. Thermographic Inspection
Thermographic Inspection is an accurate, quick, and effective maintenance technique that can
be used to avoid equipment breakdowns.
Thermography is a science which analyzes heat transfer through electromagnetic waves,
otherwise known as radiation. Every living being and inanimate object (electrical control
panels, motors, boiler doors, etc.) emits electromagnetic radiation in the infrared spectrum.
Only the infrared camera can see this radiation.
Without opening, stopping, or altering the equipment's process, the infrared camera allows us
to see the temperature variations in a visible light spectrum, both black & white or color. The
camera can display accurate temperature differences in increments of one degree. A visual
image of the entire process shows a great deal more than taking individual temperature points.
An infrared scanner looks very similar to a VCR camera. It can record the site information to a
3.5" diskette, or to a standard VHS videotape for later review and investigation. A display
screen will aid in the immediate identification of potential problem areas and allow for on-site
solutions.
In a Thermographic inspection, plant equipment is systematically scanned for temperature
profiles to find and correct developing problems before an equipment failure occurs. The
source of overheating or other problem areas can be determined by analysis.
Temperature anomalies in equipment, called "hot spots", can be investigated. The relative
severity of a "hot spot" can be determined, and the root cause isolated and identified. A
recommendation for corrective action completes the inspection report. It is important to
remember that the absence of heat or "cold spots" may also be indicators for concern.
One of the many applications of Thermographic technology is electrical inspections. The
electrical system is essentially a chain. When the chain is stressed, it will break at its weakest
point. The job of the thermographer is to find these weak links in the electrical system, before
they break. Defective components, such as poor connections, overloads and phase
imbalances can be easily found with an infrared camera. "Hot spots" of an electrical system
usually begin with a small temperature rise. As the component deteriorates, the temperature
rises until finally something burns up, or worse yet, explodes.
4. Infrared Thermography has a distinct place in the inspection of energized electrical equipment.
The electrical gear can be inspected proactively without the necessity of a system shut-down.
The benefits in dollar value, safety to equipment and personnel are immediately realized.
By predicting failures before they occur, results in savings of downtime and equipment
loss are of tremendous value. The inspection speed and accuracy of the infrared is being
utilized more now than ever before to provide reliability to electrical systems, boosting plant
productivity, efficiency, and profitability.
Additional applications of the Thermographic Inspection technology include the inspection of:
· Electrical Distribution Systems
· Industrial Process Equipment
· Boiler and Furnace Systems
· Building Insulation Integrity
· Steam Distribution Systems
BECAUSE INFRARED SCANNERS ARE NON CONTACT, THERMOGRAPHIC INSPECTION
MEASURE OPERATING CONDITION WITHOUT STOPPING MACHINERY AND WITHOUT
INTERRUPTING THE PRODUCTION PROCESS.
THERMOGRAPHIC INSPECTION is used to supplement Preventive Maintenance Programs
that can reduce downtime and maintenance expense. THERMOGRAPHIC INSPECTION
enables the elimination of some time-consuming and expensive Preventive Maintenance tasks.
Types of problems that can be found using THERMOGRAPHIC INSPECTION :
* Incipient Electrical Failures
* Loose Electrical Terminations and Connections
* Unbalance Electrical Load
THERMOGRAPHIC INSPECTION can help to discover equipment faults so that they can be
repaired before a catastrophic failure occurs. Reducing the number of equipment failures will
reduce the cost of maintenance. SAVE TIME AND MONEY with Predictive Maintenance and
THERMOGRAPHIC INSPECTION.

8. Flat Roof Thermographic Surveys
Thermographic Inspection is used to identify moisture-laden areas within roof substrates
(insulation), which gives an indication of the condition of the roofing and the location of possible
leaks.
Thermography is a science which analyzes heat transfer through electromagnetic waves,
otherwise known as radiation. Every living being and inanimate object (electrical control
panels, motors, boiler doors, roof membranes, etc.) emits electromagnetic radiation in the
infrared spectrum. Only the infrared camera can see this radiation.
Without opening, stopping, or altering the existing environment, the infrared camera
allows us to see the temperature variations in a visible light spectrum, both black & white or
color. The camera can display accurate temperature differences in increments of one degree.
A visual image of the entire process shows a great deal more than taking individual
temperature points.
The sun heats up a roof all during the day. When water leaks through the moisture barrier of a
flat roof into roofing substrates (insulation), the wet areas can be located using infrared
imaging. Moisture-laden insulation stores more solar energy than dry insulation. After sunset,
especially on a clear sunny day, the moisture soaked insulation takes longer to cool because of
the additional stored energy. Using the infrared imager in the early evening, areas of potential
roof leaks can be located by scanning for temperature differences between the wet and dry
areas of the roof.
An infrared scanner looks very similar to a VCR camera. It can record the site information to a
3.5" diskette, or to a standard VHS videotape for later review and investigation. A display
screen will aid in the immediate identification of potential problem areas. These areas
will be plotted and marked on the roof's surface for further investigation.
In a Thermographic inspection, the roof is systematically scanned for temperature profiles to
find the potential loss of the watertight integrity of the roof membrane. The source of
leaks or other problem areas can be determined by analysis, and maintenance can be planned
and scheduled accordingly.
