Jacksonville, FL 32211
Marine surveyors are to the marine industry as building and home inspectors are to the commercial and residential real estate industry. A marine surveyor’s opinions are relied upon to document the condition and value of the vessels (boats, ships) they inspect.
In continuation of his paper presented at IR/INFO 2006, Mr. Allinson will present more images and discuss how infrared imaging has been used as an effective tool in extending a marine surveyor’s ability to detect anomalies.
Images presented and discussed will include the effects of galvanic corrosion in an aluminum-hulled vessel, finding metal fasteners in wooden-hulled boats, detecting internal structures and framework in boats, and inspecting the wheels of boat trailers.
Identifying Motor Defects Through the Six Fault Zones
Bethel, Noah P.
5909C Hampton Oaks Parkway
Tampa, FL 33610
One of the biggest problems faced in analyzing electrical equipment is determining where the true problem is located.
Fault Zone Analysis should be utilized to ensure that the actual problem is being detected and not just a secondary problem caused as a result of the real problem.
This paper will discuss the diagnostic process for electric motors and outline six specific fault zones that should be looked at, which include the power circuit, insulation condition, stator condition, rotor condition, air gap and power quality.
Thermal Trending of Electro-Mechanical Equipment
Senior Test Engineer
PSE&G, Maplewood Testing Services

Maplewood, NJ 07040
Thermographically identifying problems in electro-mechanical equipment such as motors is not as straightforward as finding a hot splice on a power line. With a busy schedule and many motors to survey, documenting manufacturer’s specs on each motor can be a daunting task.
This presentation will demonstrate the use of database and reporting software in conjunction with Microsoft Excel for condition monitoring of electro-mechanical equipment.
By entering each component’s baseline thermal data as well as data from each scheduled survey into the program, the thermographer can query the database each time a survey is performed and get a listing of only those components which have shown an exception in the current and previous surveys. This will allow any deteriorating conditions to be quickly detected and repaired before irreversible damage occurs.
Infrared Thermography: Interpreting the Images
14235 SW Patricia Avenue
Hillsboro, OR 97124
Over the last couple of decades, there have been many changes to infrared imagers and audio/visual equipment that make data gathering easier and more accurate.
Since infrared thermography companies have been servicing the industrial, manufacturing, commercial, residential and so many other industries, many new applications have been developed and more are being discovered and presented at forums like this all around the world.
My time in infrared has been a learning experience. Over the last 15 years as an infrared thermographer, and 10 years in business, Oregon Infrared has performed inspections for a wide array of applications and has captured over 100,000 images.
I have run across some examples of common problems in gathering accurate data which I call “Data errors”.
In this presentation I will illustrate some of the issues I have learned from and hope to help my fellow thermographers avoid some of the mistakes I have made over the years. Also included will be some examples of tips and tricks to make an infrared survey more efficient.

Using ultrasound to scan around door seals and air vents prior to opening for an infrared inspection can help detect the presence of arcing, tracking or corona, especially if there are no scan ports in the equipment.
This multi-technology approach is recommended as an excellent tool for increasing safety of personnel while reducing the potential for an unfortunate accident.
This presentation will review the suggested methods and approaches to determing the presence of arc flash potential in enclosed, energized electrical equipment by simultaneously using ultrasound and infrared technologies.

Thermal Infrared vs. Active Infrared: A New Technology Begins to be Commercialized
Grossman, Jon L.
7520 NW 54th Street
Miami, FL 33166
What do most thermographers think the technology is when someone says Active Thermography?
Obviously, most of us think that we are doing something to create a viable thermal infrared image. However, it seems that we need to retool our words and recalibrate our minds.
This presentation will discuss the difference between Thermal IR and Active IR and, by example, demonstrate the differences not only in the wording but also in actual use.
Destructive Harmonics in the Infrared World
Predictive Maintenance, LLC
71 Gelpi Avenue
Kenner, LA 70065
The proliferation of computers and solid state electronics in the modern workplace has been accompanied by an increase in the presence of destructive harmonics within electrical distribution systems.
Symptoms of destructive harmonics include, but are not limited to: nuisance tripping of circuit breakers, blown fuses, failed motors, and overheated transformer windings and neutral conductors.
Since harmonics are often accompanied by a temperature rise, thermography can be used to detect evidence of their presence. This paper will discuss the causes, effects, and symptoms of harmonics as well as techniques for dealing with harmonics.

North Billerica, MA 01862
A thermal imaging camera taking a high definition thermogram gives one the potential to find smaller problems at greater distances that might be missed with a lower resolution thermal imaging camera.
High definition thermal imaging refers to the fine detail and clarity of a thermal image, which means it contains a large number of pixels per unit of area, which generally results in greater temperature measurement accuracy, particlarly for small objects.
This paper will discuss how a high definition thermal imager can be ideal for top-level thermographers whose work environment demands the best thermal imaging camera and technology.
Verifying an Infrared Imager’s Calibration
Peacock, G. Raymond
Southampton, PA 18966-3836
A brief walk through of why and how an individual can verify the radiometric (temperature) calibration of their infrared thermal imager and why some popular myths are untrue. There are three main obstacles to doing verification on a regular basis.
First, the equipment suppliers seldom recommend that you do it. Second, very few users have learned how to do it successfully. Finally, the uncertain but clever user can often rationalize their way out of the work by adopting popular myths like: “If the equipment exhibitors wanted me to do it, they would have told me how”; or “Even if it is not to specifications, I can’t do anything about it”; and the most popular, “I don’t need to know, I only look for temperature differences”.
This presentation will provide a more balanced and rational view of calibration and instrument performance plus provide some methods for verifying the temperature calibration of your imager and how to track it over time. Your confidence in your equipment will be more solidly based once you begin to collect real numbers instead of myths.

Infrared Windows: Where Do I Start?
Global Maintenance Technologies
Chelford Court, Robjohns Road
Chelmsford, Essex CM1 3AG
Due to the nature of electrical switchgear, 90% of the components that a thermographer wishes to inspect are normally behind cabinet doors, switched interlocks, etc., making it impracticable for the thermographer to safely and routinely inspect live switchgear.
The recognition and adoption of the safe working practices outlined in NFPA 70E have led to the acceptance of IR windows as an approved, safe method that allows live inspections to be completed while ensuring that the thermographer is safe.
However, there is still a lot of confusion regarding the implementation of IR windows into a thermographic inspection program. The most common questions regarding IR windows are:
- How do I work out where to put the windows?
- How many infrared windows do I need?
- What can I see through an infrared window?
- How do I use infrared windows?
Infrared inspection windows are a real benefit to a thermographer. They make our work safer, faster and more accurate, but only when installed and used correctly. This paper will discuss in detail the points outlined above and dispel some of the most commonly held misconceptions regarding IR windows.

The economic impact of downtime at data centers is the highest in the commercial sector.
Therefore, the return on investment of predictive maintenance activities, especially infrared, is excellent. These information technology customers want extreme reliability of the equipment, what they call “availability”.
In the last year or so, they have become interested in more efficient cooling of the server racks, so that more servers can be operated per square foot of floor space at the centers.
This paper outlines a systematic approach of utilizing infrared thermography to check many different aspects of computer center operations.
