Abstract:
Thermography is a proven technology for detecting elevated temperatures within operating electrical distribution systems. Typically performed on an annual basis, infrared inspections can detect evidence of overheating caused by loose/deteriorated connections, overloaded circuits, and imbalanced loads.
While infrared inspections can be valuable in helping to prevent unexpected failures, they provide a single “snapshot”, leaving the subject components unmonitored for the balance of the year.
Recent advances in technology have resulted in wireless sensors that monitor for the same types of defects that are detectable by thermal imaging. When permanently installed on electrical enclosures, these sensors can provide year-round monitoring of electrical system components and can immediately alert personnel when problems arise.
This paper will discuss the theory and application of the Delta T Alert monitoring system and how it can be used to complement and enhance the effectiveness of an existing infrared inspection program within commercial office buildings. A few case studies showing the effectiveness of Delta T Alert will also be presented within this paper.
What Do You Mean Compressed Air Isn’t Free? We Breathe It Every Day!
Bandes, Alan
Abstract:
Compressed air surveys can dramatically reduce plant overhead and have a positive effect on the air we breathe. Compressed air isn’t free and compressed air leaks actually impact the air we breathe.
Compressed air is almost ubiquitous in many facilities. It is used, and at times misused, to regulate controllers, power tools, or move products through processes. It is also a large source of wasted energy. It costs a lot of money to produce and use.
Yet, there are many people directly involved with this utility that have the misunderstanding that it is cheap and almost “free”. For this reason, compressed air is often misused and leaks a left alone as “background noise”. The US Department of energy has estimated that 30% of all compressed air produced in the US is lost to leaks.
If you calculate the loss in dollars, this can add up to approximately $3.2 billion!!! Now, add the impact on the environment with the build up of carbon dioxide, nitrogen oxide and sulphur dioxide (the “carbon footprint” gases), and the cost extends beyond the plant to our planet.
Unfortunately, it almost seems like a cliché to read or hear about energy conservation and its impact on our planet in a way that is good news, since people are now aware of the need to reduce energy use.
The bad news is that very few actually do anything about it and even worse, there are many more that do not understand how easy it can be to cut energy costs and reduce their carbon footprint, especially many of us in the industrial/commercial sector.
This presentation will discuss the logistics of a compressed air leak survey and new developments in software that will help you learn how to manage a compressed air leak survey, assure repairs have been made, and report the results to management. In addition to calculating the cost of air leaks, it will report on carbon footprint savings from the survey.

Abstract:
The ever present emphasis on technological efficiency is just one of several forces behind the pressure on companies to “go green” despite a trying economy.
The ultimate criterion that determines whether a motor is truly green is energy efficiency. Technology, long the key to efficiency, can help resolve this issue through detailed computerized analysis of the motor, the power environment in which it operates, and even its reliability.

Abstract:
Since the 1970’s, thermal imaging has been utilized to diagnose the thermal performance of commercial and residential buildings. Rising energy prices combined with greater public awareness have created record demand for professional thermographers as building owners focus their attention on energy conservation and building performance.
Having a well thought out plan of execution, from selling the job to completing the final report will increase the likelihood of success when performing infrared inspections on large building complexes.
This paper details infrared inspections of a 1,500 room hotel and adjoining convention center with a combined total flat roof area of over 500,000 square feet and exterior wall heights in excess of 100 feet. To accomplish this project, a phased approach was used that included aerial infrared and follow-up walk-on roof inspections, exterior wall inspections, and interior inspections investigating specific problem areas.

Abstract:
Testing and balancing of HVAC systems is important not only for energy and design requirements, but also for the comfort of building occupants.
It’s not easy to see if someone is uncomfortable and impossible to make everyone comfortable. Testing involves many instruments – most of which measure temperature, volume, and velocity of fluids, with air being one of those fluids.
Air movement is a necessary requirement in buildings. Where and how air moves is not easy to control once it leaves the ductwork.
Although chemical smoke is often used to study air currents, it does not indicate the thermal effect of air currents which can affect the comfort of occupants.
This paper will discuss the use of thermal imaging to study building air currents associated with the HVAC system. It will also discuss how thermography can aid in improving occupant comfort and HVAC system performance.

Abstract:
You just called one of your major customers to schedule their annual inspection and they let you know that they will not need your infrared services this year.
You asked them why, since you have been giving them good professional service for the last 5 years, and they tell you that they chose another company who charges $50 a day less for the inspection.
This is the third large customer that you have lost in the last 3 months. You ask yourself: “What is happening and how can I stop it?”
In today’s marketplace, with a recession/recovery going on and many customers with tight budgets, how do you differentiate your infrared business from the others?
In this paper, I will discuss “competitive advantage” in the infrared industry, trends to watch and capitalize on, and what has worked for other successful infrared companies.

Abstract:
Infrared imaging of industrial enclosures such as processing tanks, pressure vessels, and heat exchangers has historically been performed on a random basis to record levels of fluids and solids.
The results of the scanning always reveal and support some process control management for that specified condition and time, but the aspects of more elaborate condition process and monitoring techniques to support a wider scope imposes many challenges in development of the infrared technology and tools in all parameters.
Detecting Median Mononeuropathy and Carpal Tunnel Syndrome through Radiometric Thermal Imaging
Edwards, Shay
University of California Riverside
Computer Sciences Corporation
NSWC Corona Division
951-735-9003
Abstract:
The primary objective of this study was to determine if radiometric thermography could detect Median Mononeuropathy in the articulatio radiocarpalis. A secondary objective was to establish the efficiency of thermal imagery as a viable technique for establishing the trends of Carpal Tunnel Syndrome and Median Mononeuropathy.
Whereas an x-ray indicates structural anomalies, thermography can point out functional anomalies. In this study, participants were instructed to use their dominant hand to repetitively squeeze a rubber ball for a brief period of time. A thermal imager was then used to image and record temperatures across the subject’s wrist area.
Subjects known to have carpal tunnel syndrome or Median Mononeuropathy exhibited elevated temperatures in the wrist area. Similar results were observed in subjects with compromised circulatory systems even though they had not been previously diagnosed as having carpal tunnel syndrome or Median Mononeuropathy.
This research suggests that thermal imaging offers potential to identify predisposition to Median Mononeuropathy not related to repetitive motion.

Abstract:
Underground feeder cables are a critical component of Con Edison’s electrical distribution network.
Operating at voltages of up to 13,000 volts, underground feeder cables are a common feature in the City of New York and surrounding areas. Like above ground conductors, these cables are subject to failures associated with loose/deteriorated connections, overloads, and unbalanced loads.
Recognizing that thermal imaging could detect incipient cable faults, Con Edison undertook a research project to correlate typical underground cable faults with infrared imagery.
This paper will discuss the results of laboratory results and how Con Edison is utilizing thermal imaging to help ensure underground power cable reliability.
Resistance in Circuit Breakers
Garber, Warren C.
NETA Test Technician, Infraspection Level III Thermographer
Industrial Electric Testing, Inc.

904-260-8378
Abstract:
As thermographers, we see many thermal anomalies in switchgear and panelboards. However, finding the actual root cause of what appears to be high contact resistance is not as straightforward as you may think. Circuit breakers have many internal mechanical connections, all of which can radiate heat under load.
Misdiagnosing thermal anomalies can result in added time, wasted money and unnecessary damage to critical equipment. Additionally, there is the frustration involved with finding that same problem during the follow-up inspection, and then having to explain to the customer or your boss why the money that was spent to tighten the “connection problem” didn’t rectify the problem.
In this presentation I will discuss the parts of circuit breakers and the ways that those parts can cause thermal anomalies commonly called “connection problems”. I will show, using a primary injection test set, how different connections within the breakers will produce thermal anomalies and I will then demonstrate a voltage drop technique to determine the location of the abnormal resistance.
Quantitatively Correlating Gold Cup Pyrometer and Infrared Thermography Data of A Steam Reformer’s Tubes

868-653-9343 / 868-657-6572
Abstract:
Maintaining proper reformer and process heater tubes temperatures within petrochemical plants is critical to the life of the tubes. Reformer and furnace tube replacement is extremely costly and time consuming. Furthermore, tube failures can potentially escalate to catastrophic failure of the vessel or even plant.
However, acquiring accurate tube temperature is extremely difficult and often misunderstood. Plant operators and engineers routinely measure their own temperatures using handheld spot pyrometers or thermal imagers, however unless there is an accepted means of acquiring actual contact reference temperatures, any non-contact temperatures measured will be inaccurate within a range outside the acceptable error tolerances.
This paper will discuss an actual exercise conducted on a multi-row box type steam reformer to determine the viability of acquiring quantitative temperature data within acceptable tolerances using a gold cup pyrometer as the contact reference and a radiometric thermal imager as the non-contact working thermometer.

Spectral Emissivity in Infrared Applications
Peacock, G. Raymond

Skype: grp362
Abstract:
One of the prime factors in accurate temperature measurement using infrared thermography is the often maligned and much misunderstood parameter of spectral emissivity. Many times in making thermographic images, it is necessary to correct for an object’s spectral emissivity. Using an incorrect value can cause large errors. Sometimes, just making an emissivity correction can add extra error into the measurement.
This tutorial will discuss when and how to use spectral emissivity without knowing any actual values.
Next, it will review just how one can find a practical value to use in a given measurement situation.
Finally, it will introduce some resources to help guide your choices. Please note that the term “spectral emissivity” is the more precise term for the correction needed, simply because the different spectral responses for individual thermal imaging cameras and spot infrared thermometers and different responses can often mean different correction values.

4914 Lena Road, Suite 105 Bradenton, FL 34211
941-907-9128
Abstract:
Infrared windows provide a cost-effective and safer alternative to traditional inspections. This paper will discuss how this mill realized a return on investment very quickly while benefiting from the other intangibles of infrared windows.
Namely: The ability to inspect the previously un-inspectable equipment; the ability to inspect critical applications more frequently; the ability to more aggressively monitor any applications which are suspected to be running to failure; increase in safety for personnel; decrease in risk to plant assets and operations due to non-invasive nature of inspection – safeguarding profitability and freeing up critical personnel who can be utilized for other valuable jobs in the plant rather than removing and reinstalling panels.
Case studies will also be presented.
