Dusty Birge, UAV Recon
Traditional thermography concepts for substation and line patrol include primarily ground-based methods. UAV Recon, an unmanned inspection service provider, has completed many successful substation inspections, both daylight and nighttime. Utilities are anxious of drones flying around a sub, and drone service companies struggle to prove the technical benefits to â€˜get in the door.' With a substation service backgroundâ€¦we bring both substation & aerial technical experience. We will illustrate the aerial substation thermography techniques we utilize for SAFE & EFFECTIVE aerial inspections.

Proper Identification of water intrusion of a roof system will ultimately save Captial budgets. As Capital Improvement budgets become tighter, the need to prioritize the areas of remedial action is critical. Working with a campus type infrastructure with multiple buildings, identifying the systems with the most need prioritizes how long one systems life can be extended over another. With regular monitoring it is also possible to identify areas of water infiltration before the leak is encountered within the space. Although UAV techniques can greatly increase the areas which can be preliminarily investigated, the need to have "boots on the ground" can not be completely eliminated. Standing water, dust/dirt accumulation and different roofing materials can give a multitude of thermal signatures which could or could not be indicative of a system failure. To create a cost effective program for a facility, the understanding of thermal imaging must be coupled with knowledge of roofing systems. One without the other can be counter-productive for the client.
Currently employed as a Facility Engineer a large manufacturing facility (>1.5M sq ft) with responsibility for roofing, building maintenance and new construction. Currently planning level III certification. Responsible for Thermal Investigation of roofing, high voltage electrical distribution and large machine predictive maintenance.

I will visit several Mexican food restaurants and measure the temperature of the tortilla chips when they arrive at the table. I will then choose which location has delivered the chips closest to the proper temperature, according to my personal preference: the hotter, the better. I will also place an order for guacamole and make the same judgment based on my personal preference: the closer to room temp, the better as I prefer my guacamole not to be cold.

Atlantic is currently in our 19th year of LNG operations. Increasingly, this requires us to manage and understand the new challenges that present themselves as a Facility of this nature ages. Discussions were held to determine how we could harness technology to aid us in sustaining safer operations and reducing operating risk. The Infrared Optical Gas Imaging program highlighted in this paper is a direct result of this initiative. At Atlantic, the Condition Monitoring Team utilizes Forward Looking Infrared ("FLIR") Technology as part of our "Predictive Maintenance Strategy" to provide information on equipment "health" as well as in Hydrocarbon Gas Emission Detection. It also aids in effective maintenance management and prevention of equipment failures. Infrared Thermography is a non-contact, non-destructive technology that provides a temperature profile of the equipment being evaluated. Infrared thermal imagers are a special type of camera that "see" the heat radiated from different types of equipment. Where thermo-grams are in black and white, white is an indication of hot and black, an indication of cold temperatures. If thermo-grams are in color, normally white and red areas are hotter and black and blue areas are colder. All Condition Monitoring Analysts are American Society for Non Destructive Testing (ASNT) certified Infrared Thermographers and have also been trained in Advanced Gas Detection which allows for the maximization of the potential application of this technology. Main FLIR units currently in use are the FLIR GF 320 for Gaseous Emission Detection and the T1K Thermal Imagers used for Mechanical / Electrical surveys. The imagers differ in optics and wavelength sensitivity as well as cost due to the applications for which they have been designed. The successful results that have been realized to date from these imagers have demonstrated that the investment in this technology has been very worthwhile.
Randy P. O'Rosco has been a Condition Monitoring professional for the past 12 years. He is an ASNT NDT Level II Thermographer and currently, Team Lead - Condition Monitoring at Atlantic LNG Company of Trinidad and Tobago where he is accountable for the Infrared Thermography program at the 15 MTPA LNG Facility. Randy had a key role in setting up Atlantic's current Infrared Optical Gas Imaging Program and together with his team of Thermographers, brought it to the success it is today. Randy is also an ISO Category III Vibration Analyst and has recently achieved Certified Maintenance and Reliability Professional (CMRP) status in 2017.

In the 1950's Infrared was basically limited to the Military or Government use, as the cost of these systems was extremely high and the size of the cameras where huge. By the 70's and 80's, more and more industries starting using Infrared as part of their inspections, but the number of users was still small based on cost. Today, you can buy a good Infrared camera for under $500 and a great camera for under $8000. More and more companies are buying these cameras and deploying them within their facilities. Infrared is a powerful, noninvasive tool, but understanding its limitations is critical. You will quickly see infrared thermal imaging equipment is not difficult to learn or use. Unfortunately it is also not difficult to make very serious mistakes interpreting what you see. The most common mistake that people make is forgetting to think. Thermal imaging equipment is simply a tool. You must also think about how that information can best be used to solve problems. To do that you need to remember to think! The following case studies will illustrate the proper use of Infrared Imaging for Mechanical Inspections.

The purpose of the article is to present IR thermography as an effective predictive maintenance technique and to demonstrate the possibilities of the wide use of this application in the energy sector. I would like to present, in particular, typical faults on the equipment at the plant, which were detected using IR thermography and which are result of a large number of thermographic measurements carried out over a longer period of the time. In electric power systems, malfunctions are often reflected in local temperature rises. Local overheating can be due to increased contact resistance, friction, increased electrical load, induction, leakage of closing elements in pipelines, and etc. In addition to local overheating, the absence of heating on elements such as capacitors, resistors, conductors and similar componnets, which may have to be heated to a certain temperature during normal operation, may also be a sign of an error. In order to detect such errors, we perform periodic thermographic inspections. At the KrÅ¡ko Nuclear Power Plant, Slovenia, we use IR thermography as a predictive diagnostic method since 1992. The use of this non-destructive predictive technique contributes to greater reliability and availability of equipment, and indirectly to increased fire safety. In the article is presented number of various practical examples of IR Thermography aplication in the Nuclear Power Plant. Systematic surveillance and knowledge of diagnostic methods contribute early detection of faults, inappropriate operating conditions and they help to assess the quality of maintenance activities. Good knowledge of the diagnostic method itself, knowledge of the measuring equipment and knowledge of the production process and equipment are very important for quality measurements and error detection. In the analysis of errors and failures, however, the results of preliminary measurements on the same or the same components, operational experience and frequent monitoring of the error development are very important.

While working in the arctic oil fields over the last several years, I've had the opportunity to spot wild polar bears in their natural habitat. On several occasions, I had to stop work, because a polar bear was in the area and could not be located. As an infrared thermographer, my natural first thought was to use infrared to find these bears. I was informed: "Polar bears are invisible to infrared cameras, because they have thick, insulating fur which traps all of their body heat." This statement led me on a quest to determine if a polar bear could, in fact, be seen on an infrared camera. I spoke to members of the security and environmental teams employed by the oil companies, Polar Bears, and Alaska Fish & Wildlife, and I gathered information on how these groups utilize infrared to spot and track polar bears. They provided me with information and the techniques that they employ; they also offered me infrared images of polar bears and their dens. I set about to capture my own images of polar bears and their thermal signatures, which I would like to share with the infrared community.
My name is Harley Denio III, I have been working with infrared continuously for the last 16 years and am the president of Accurate Infrared LLC. We operate out of the NW but provide Infrared services across the US and abroad. Additionally, I have spent the last 5 years working in Alaska in the Prudhoe Bay oil fields which has inspired me to write this paper.

Unintended Consequences of Bearing Maintenance by Hank Herber, Maintenance Coordinator III â€“ Maintenance & Site Service Division Maintenance Programs and Paul Ruston Parker, Power Plant Engineer â€“ Engineering Services-Utilities and Institutional Facilities Engineering.
Los Alamos National Laboratory's (LANL) Steam Plant delivers heating and process steam to 3.2 million square feet of computing facilities, scientific laboratories and administrative facilities with in the central TA-3 campus. The plant consists of three (3) natural gas fired boilers with backup diesel fuelâ€“firing capabilities, each capable of producing over 100,000 pounds of steam per hour. Continued reliable steam generation is an essential function at the heart of the Laboratory's mission. In the month of November, when temperatures typically drop below freezing and steam demand is at its peak, an anomaly was discovered on a critical piece of power plant equipment using infrared thermography. The butt end of the outboard fan bearing temperature was found to be 450Â° F, almost 350°F above normal operating temperature. The elevated bearing temperature indicates imminent failure, which could have a significant detrimental impact on steam generation.

Regular visits of a sauna are considered to support the immune system and they are very popular in middle and northern Europe. In Germany many new home owners already plan for a private sauna either inside their house or standing isolated outside in the garden. A sauna is characterized by rather high temperatures differences between inside (e.g. 60Â° up above 100°C in Finnish type saunas) and outside (from room temperature if inside a house to well below freezing in wintertime for garden saunas). Whenever large temperature differences are present, there may also be large associated heat transfer rates. Obviously using a sauna is just for leasure and the user usually does not care too much about the waste of energy or CO2, still any home owner wants to build/construct his sauna as energy efficient as possible in order to save heating cost. The present paper studies the thermal insulation of two wooden sauna types, an indoor sauna and an outdoor one with thermography and heat flux measurements. The aim was to find potential structural defects and leakages of the thermal insulation. We present results, discuss potential problem areas and suggest how the energy consumption may be reduced.

Acid Tank Cleaning Problem 4000 gallon sulfuric acid tank with estimated 3000 gallons of product flagged for decommissioning. Initial plan to vacuum liquid acid from tank then begin cleaning and neutralization failed due to acid precipitate in base of tank too dense for vacuum removal. Company acid tank cleaning protocol calls for removal of acid and acid products prior to introduction of water. Neither the volume of water required to exhaust the exothermic reaction nor the magnitude of the reaction are known. Viable safety and environmental mitigating contingencies are imperative to proceed. Approach Contract specialty chemical cleaning service with experience in addressing this scenario with plan to deluge up to 3000 gallons of corrosion inhibited water into the tank through a multi-directional two axis rotating nozzle. Establish an inerting nitrogen gas purge within the tank prior to water introduction and alkaline scrub the rapidly expanding gases liberated during the reaction through the tank's vent. Monitor the tank's wall thermographic signature with a FLIR P660 to identify the thermal plateau and decline indicating the exothermic reaction has depleted. Outcome Planned approach executed without incident while tank wall thermogram videoed with the P660. Electric Generator Collector Brush Rigging Current Balance Problem GE 7FH2 gas turbine driven electric producing hydrogen cooled generator magnetic field is established by imparting DC excitation voltage into the field wound rotor. The excitation voltage is imparted into the ~45 ton field rotating at 3600 rpm via carbon brushed in contact with the collector ring. Electrical current imbalances can begin to occur due to brush wear, collector ring runout, collector ring fouling and other effects. As some brushes begin carrying more electrical current than others, if allowed to continue unchecked can lead to brush overheating. Uncorrected brush overheating can lead to a collector catastrophic event referred to as 'flash over'. Approach Collector brush rigging preventive maintenance techniques typically involve a technician checking and trending individual brush amperages and vibration. Both techniques involve physical contact with the energized brushes in close proximity to the rotating collector ring. IR scans are being explored as non-physical contact brush condition diagnostic indicators. Outcome Undetermined at this time; however interested in whether any other Thermographers have established a similar predictive program.

Thermography is an established technique for such a large number of different applications that it is difficult to find a single resource for researchers as well as practitioners in the field, for beginners as well as for experts. In 2010 we had presented a respective book: "Infrared thermal imaging — fundamentals, research and applications" which gave a straightforward introduction to thermography. Due to the modular structure, readers could start studying whatever they liked, be it the theoretical background of cameras, detectors, thermal radiation and heat transfer or be it for example applications for teaching, building science, detection of gases, the study of micro systems. In addition, examples of electrical and miscellaneous industrial applications were presented as well as medical and veterinary studies, the use of IR imaging in sports, arts, surveillance and investigations in nature. IR imaging is, however, such a very rapidly evolving field that eight years is nearly an eternity. Meanwhile there exist a multitude of new cameras with new detectors, new data handling facilities, new software solutions, and most important also many new applications. Therefore we completely revised and expanded the existing text, and also added a new chapter to reflect recent developments in the field and report on the progress made within the last decade. Strong focus is on real-life examples, with 20% more case studies taken from science and industry. For ease of comprehension the text is backed by more than 590 images which include graphic visualizations and more than 300 infrared thermography figures. The latter include many new ones depicting, for example, spectacular views of phenomena in nature, sports, and daily life. This new 2018 hard cover 2nd edition with more than 760 pages and about 600 images mostly in full color may either serve as textbook for beginners or as handbook for expert practitioners: it is the ultimate resource for every user of thermography.

In order to obtain the data, a test bank was constructed, which was iterated in two stages based on the methodologies proposed by Taguchi for the design of experiments [Montgomery, D. C., and Wiley, J. (n.d.). D esign and Analysis of Experiments.]: Characterization in which the flow is understood, and optimization in which it maximizes the cooling capacity. The bench is made using acrylic, steel and the fixing structure manufactured by José Edgardo Niño, its rigidity is improved by fixing to the floor after the recommendations made by . It is instrumented by using the NI USB-6212 with rotation sensors for the instantaneous conductor and conduction speeds, thermocouples for average temperature in the exits and the surface temperature dropouts in the components using the FLIR T300, flow lines with the high velocity speed recorded. Based on the tests carried out an improvement was achieved at 3800 RPM reducing the temperature without load of the belt and in the first five minutes in 12.9°C 3.9°C more than the previous model.

"In chemical industry plants, the raw material, intermediate and final products can leak from unstable joints of flanges and valves as well as cracks of storage tanks. From the safety and economic standpoints, it is very important to understand whether leaks or not and leakage rate. The OGI(optical gas image) technique can tell gas leakages, but cannot give the leakage rate. Some special OGI devices can show the kind of gas in different color concentration in different darkness. Therefore the research on quantification of OGI is necessary.
In this research, we have developed the practical method to quantify OGI of methane leakage. To estimate 3-dimensional gas leakages distribution from 2-dimensional OGI, the Monte Carlo Probability technique was applied. First, the number of points in the area of width(2.54 ãŽ�) and length(2.54 ãŽ�) in OGI was counted. Total number of each experiment was compared with the measured flow rate. The correlation average between total points and measured flow rate was found to be 0.980. Reversely we estimated the leakage rate of OGI by use of the correlation table. The results showed good agreement between the estimation value and the measured value."

In my presentation I will demonstrate how our technicians here at John Deere Reman Electronics use our FLIR E6 thermal imaging camera for troubleshooting purposes. I will demonstrate how we collected our baseline data using a known good circuit board powered-up in normal testing conditions. I will then present how our team uses thermal imaging to search for components on a malfunctioning circuit board by comparing the images of both circuit boards. I will demonstrate how we find faulty components not only by their higher than normal temperature but also the lower temperatures of open components that are not conducting electricity. No conduction means no current flow which means no heat dissipation. In my presentation I will have the two circuit boards running at normal operation and show the differences with the thermal camera.
I work at John Deere Reman Electronics as an engineering team supervisor. At this division of John Deere we remanufacture electronic equipment including include Display Monitors, Engine Control Units, Electronic Control Units, and Moisture Sensors. My team is responsible for designing and maintaining the test equipment used to ensure our customers our products meet or exceed our quality standards.

Monitoring volcanoes have been on the past decades an expanding matter, one of the rising techniques that involve new technology is the digital video surveillance, and the automated software that come within, now is possible if you have the budget and some facilities on site, to set up a real-time network of high definition video cameras, some of them even with special features like infrared, thermal, ultraviolet, etc. That can make easier or harder the analysis of volcanic phenomena like lava eruptions, phreatic eruption, plume speed, lava flows, close/open vents, just to mention some of the many application of these cameras. We present the methodology of the installation at Poás volcano of a real-time system for processing and storing HD and thermal images and video, also the process to install and acquired the HD and IR cameras, towers, solar panels and radios to transmit the data on a volcano located at the tropics, plus what volcanic areas are our goal and why. On the other hand we show the hardware and software we consider necessary to carry on our project. Finally we show some early data examples of upwelling areas on the Poás volcano hyper acidic lake and the relation with lake phreatic eruptions, also some data of increasing temperature on an old dome wall and the suddenly wall explosions, and the use of IR video for measuring plume speed and contour for use on combination with DOAS or FTIR measurements.

Mobile apps that integrate thermal imaging and sensing can be excellent tools for creating more demand for a professional thermographer's services and products â€“ and can also enable thermographers to do what they do more effectively and efficiently. Industry-leading companies like Owens Corning (construction and energy efficiency), United Infrared (home inspection), and Vernier (education) already offer mobile apps that work with the FLIR ONE and many other companies have developed similar apps for in-house use that aren't on the market. FLIR's new, integrated mobile SDK enables mobile apps to work directly with a wide range of FLIR Wi-Fi-enabled thermography and test & measurement devices, making it possible for thermographers to offer unprecedented functionality in apps of their own. By joining the FLIR developer program professional thermographers get free access to tools including the SDK they need to create and launch mobile apps, and by collaborating with FLIR and their FLIR-certified app developers they can keep development costs down and greatly accelerate time to market. In this paper the author presents three keys to help thermographers unlock the potential of thermal-enabled mobile apps: 1.) embracing mobile apps to create new awareness and demand, 2.) using the resources provided by the FLIR Developer Program to open the door to thermal-enabled mobile apps, and 3.) collaborating to create and launch a mobile app quickly while keeping development costs down.
Cal manages the global FLIR Developer Program and has worked closely with application developers, hardware designers, industry experts, and certified thermographers on mobile applications for the past 6 years. He has worked in the electronics and imaging industries for over 28 years and is excited at the opportunity to use thermal imaging and sensing in mobile apps to change the way people interact with the world around them.
