Advances in Applications and Methodology for Aerial Infrared Thermography Aerial infrared applications can be divided into two types; those where a straight-down view and/or a large area view is needed and those where long distances must be covered in a limited amount of time. Selection of aircraft, aircrew, navigational aids, infrared imaging system, data acquisition and image processing system are all important to a successful survey. This paper discusses the ongoing advances in methodology, platform and equipment required to produce high quality usable data for the end-user.
Advances in Selected Applications and Methodology for Aerial Infrared Thermography In applications where a straight-down view or large area view is needed; or where long distances must be covered in a limited amount of time, aerial infrared thermography is superior to ground-based infrared. The selection of the aircraft, camera mount, infrared imager, navigational aids, recording medium, workstation computer equipment, pilot and crew are critical to success. There are inherent dangers to flying low, slow and in the middle of the night. The job must be done right and safely-the first time. This paper focuses on recent and ongoing advances in methodology, platform and software that will bring the end-user a superior product.
Aerial Infrared - An Asset Management Tool for District Heating System Operators The imagery (IR) from aerial infrared thermal surveys of facilities, complexes, campuses, military bases and cities can be used for many purposes. Systems like supply steam and condensate return lines, hot water lines, chilled water lines, supply water mains, distribution piping, storm water drains and sewer lines can be monitored by looking at surface temperatures/patterns. In the case of district heating systems, the distribution system can be flown rapidly and inexpensively to provide thermal data for asset management planning and predictive maintenance (PdM). As a result of finding and repairing leaks in the steam system, energy usage can be reduced with all the related benefits.
Aerial Infrared Roof Moisture Surveys Infrared predictive/preventive maintenance techniques are not limited to annual infrared surveys of electrical switchgear. For instance, infrared thermography can be a very effective tool for roof asset management.
Aerial Infrared Roof Moisture Surveys Infrared thermography a very popular means of testing electrical and mechanical systems. Almost everyone in maintenance has seen an article about how infrared (IR) thermography has saved a piece of electrical switchgear from an imminent destruction and the resulting downtime. Infrared thermographers look at the thermal energy that is emitted from an object or group of objects, explain what is normal, see abnormalities and report them so that maintainers can act to repair the problem. This method works well on heat emissions from most objects, including building roofs. A well-prepared, graphic and accurate map of the infrared signatures of a roof can significantly benefit the building owner at all stages of that roof’s service life. This type of testing is commonly referred to as an infrared roof moisture survey. Infrared thermography is not leak management, it is predictive maintenance. No matter how the water got into the substrate, the purpose of this type of survey is simply to find and document where the water is so repairs can be accomplished.
Aerial Infrared Thermography-Linking thermal mapping results to CAD and GIS systems When you need a thermal image of an area, aerial IR (infrared) thermography is superior to ground-based infrared in applications where a straight-down and large-area view is needed and where large areas and long distances must be covered in a limited amount of time. Most aerial IR imaging is performed at night because daylight solar radiation tends to adversely affect the imagery. Applications of aerial IR thermography include roof moisture surveys, environmental impact surveys, animal counts, wide-area thermal mapping, landfill fire examination, underground steam system surveys, electrical power line surveys, and search and rescue operations.
After the Switchgear
After the Switchgear The practical use of infrared thermography is, in a nutshell: looking at the thermal energy emitted from an object, explaining normality, seeing abnormalities and reporting them in a graphic, usable and easy-to-understand fashion, so that someone who is not familiar with the technology, can act to fix whatever is wrong. This works on heat emissions from all types of energy - not just electrical energy. There are many uses for infrared thermography other than inspecting electrical switchgear. In this paper I will discuss two of those other uses for infrared thermography.
Application and Methodology for Locating Stormwater Discharges using Aerial Infrared Thermography This paper describes the need, application, methodology and equipment required to perform aerial infrared surveys of stormwater drainage systems and waterways to identify specific areas where leaks are occurring so that action can be taken to abate the leaks. - requires free Adobe Acrobat Reader for viewing.
Application and Methodology for Locating Stormwater Discharges using Aerial Infrared Thermography The US Environmental Protection Agency (EPA) has identified contaminated surface water and drinking water supplies as one of the most serious environmental problems facing the United States. Leaking sewage collection lines, stormwater drain discharges and illegal taps into stormwater drainage systems can be identified by their thermal infrared signatures during certain times of the year. As these sources of pollution leak, seep or empty into creeks, streams, rivers and lakes, their thermal signatures vary from their surroundings and they can be pinpointed accurately from the air by using aerial infrared thermography. This paper describes the need, application, methodology and equipment required to perform aerial infrared surveys of stormwater drainage systems and waterways to identify specific areas where leaks are occurring so that action can be taken to abate the leaks.
Applications for Aerial Infrared Thermography In certain applications, aerial infrared thermography is superior to ground-based infrared. Examples include roof moisture surveys, some environmental surveys, animal counts, wide area thermal mapping, landfill fire examination, underground steam system leaks, electrical power line surveys and search and rescue operations.
Applications for Infrared Thermography at Computer Centers Downtime at Computer Centers is not an option! The equipment is expensive and even more important, the downtime created by a failure can be extremely costly – much more than the average office building or factory. Electrical and mechanical infrared predictive maintenance (IR/PM) is a must for the safe, continuous operation of the facility and the steady flow of information. - requires free Adobe Acrobat Reader for viewing.

Finding pollution with aerial infrared thermography The Environmental Protection Agency (EPA) has identified contaminated surface and drinking water as one of the more serious environmental problems facing the United States. Leaking sewage-collection lines, storm-water drain discharges, and illegal connections to storm-water drainage systems can be identified by their thermal infrared (IR) signatures during certain times of the year. As these sources of pollution leak, seep, or empty into creeks, streams, rivers, and lakes, their thermal signatures vary from their surroundings, and aerial IR thermography can accurately pinpoint them.

NOT the Low-hanging Fruit of Infrared Thermography Over the past fifteen years, infrared thermography has gained acceptance as the way to check electrical circuitry for loose connections and other unsafe and wasteful conditions. This is a proven application and what the majority of infrared service providers do for a living. However, most of us know there are many uses for infrared thermography other than inspecting electrical switchgear. This paper discusses some of those applications as well as some new techniques for performing and promoting traditional infrared thermography.
Predictive Maintenance of Underground Heating Lines Based on experience with the underground heating networks of Russian cities, this paper suggests that remote inspection of underground heat supplying systems on the basis of aerial infrared thermography (AIT) is able to find latent leaks of hot water and other imperfections (malfunctions). Moreover, it argues that AIT data allows forecasting the places of future leaks and efficiently choosing the zones of heating lines for high-prior reconstruction, according to their actual technical condition, rather than their age.
Preventing Electrical Fires, Building Shutdowns, and Equipment Damage Using Infrared Thermography
Qualitative Infrared Roof Moisture Surveys-Who Performs Them, Who Buys Them, and Why Qualitative infrared thermography is performed on roofs to quantify the extent of roof moisture (water) that is in the roof system. Infrared thermography is not leak management. No matter how the water got into the substrate, the purpose of this type of survey is simply to find and document where the water is located. This information is then used to manage roof assets more effectively. By knowing where and how much water is in the roof, the owner can make an informed decision regarding maintenance activities that need to take place.
Repair Prioritization Based on Real Factors
Should panel covers be removed to perform an IR survey of electrical switchgear As infrared thermographers, from time to time we are asked if we could perform an electrical infrared survey without removing the panel covers…that it might be a more efficient way to perform the survey. This is a great question. It would be more efficient, but an IR survey should not be accomplished in this manner.
