1 Warnings & cautions

10474103;a1
This equipment generates, uses, and can radiate radio frequency energy and if
not installed and used in accordance with the instruction manual, may cause inter­ference to radio communications. It has been tested and found to comply with the limits for a Class A computing device pursuant to Subpart Jof Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference when operated in a commercial environment. Operation of this equipment in a residential area is likely to cause interference in which case the user at his own expense will be required to take whatever measures may be required to correct the interference.
An infrared camera is a precision instrument and uses a very sensitive IR detector.
Pointing the camera towards highly intensive energy sources – such as devices emitting laser radiation, or reflections from such devices – may affect the accuracy of the camera readings, or even harm – or irreparably damage – the detector. Note that this sensitivity is also present when the camera is switched off and the lens cap is mounted on the lens.
Each camera from FLIR Systems is calibrated prior to shipping. It is advisable that
the camera is sent in for calibration once a year.
For protective reasons, the LCD (where applicable)will beswitched off if the detector
temperature exceeds +60 °C (+149 °F) and the camera will be switched off if the detector temperature exceeds +68 °C (+154.4 °F).
The camera requires a warm-up time of 5 minutes before accurate measurements
(where applicable) can be expected.
In certain outdoor conditions, the sun can enter the eyepiece and cause damage
to the LCD. Use an eyepiece protector when you expect to be using the camera for extended periods of time in outdoor sunlit environments.

3 Welcome!

Thank you for choosing the ThermaCAM™ P45 infrared camera. The ThermaCAM™ P45 infrared condition monitoring system consists of an infrared
camera with a built-in 36 mm lens, and a range of accessories. The infrared camera measures and images the emitted infrared radiation from an object. The fact that ra­diation is a function of object surface temperature makes it possible for the camera to calculate and show this temperature.
The ThermaCAM™ P45 camera is dust- and splash-proof and tested for shock and vibration for use in the most demanding field conditions.It is a handheld, truly portable camera, which is lightweight and operates for more than two hours on one battery pack. A high-resolution infrared color image is provided in real-time in the integral viewfinder.
The camera is very easy to use and is operated by using a few buttons which are conveniently placed on the camera, allowing fingertip control of major functions. A built-in menu system also gives easy access to the advanced, simple-to-use camera software for increased functionality.
To document the object under inspection it is possible to capture and store images on a removable CompactFlash card. It is also possible to store, together with every image, voice comments by using the headset connected to the camera. The images can be analyzed either in the field by using the real-time measurement markers built into the camera software, or in a PC by using FLIR Systems's software for infrared analysis and reporting.
3
In the PC, the images can not only be viewed and analyzed, but the voice comments can also be played back. FLIR Systems’s software makes it very easy to create complete survey reports (containing numerous infrared images, photos, tables etc.) from the inspections.

7 Introduction to thermographic
inspections of electrical installations

7.1 Important note

All camera functions and features that are described in this section may not be sup­ported by your particular camera configuration.
Electrical regulations differ from country to country. For that reason, the electrical procedures described in this section may not be the standard of procedure in your particular country. Also, in many countries carrying out electrical inspections requires formal qualification. Always consult national or regional electrical regulations.

7.2 General information

7.2.1 Introduction

Today, thermography is a well-established technique for the inspection of electrical installations. This was the first and still is the largest. the largest application of ther­mography. The infrared camera itself has gone through an explosive development and we can say that today, the 8th generation of thermographic systems is available. It all began in 1964, more than 40 years ago. The technique is now established throughout the whole world. Industrialized countries as well as developing countries have adopted this technique.
Thermography, in conjunction with vibration analysis, has over the latest decades been the main method for fault diagnostics in the industry as a part of the preventive maintenance program. The great advantage with these methods is that it is not only possible to carry out the inspection on installations in operation; normal working condition is in fact a prerequisite for a correct measurement result, so the ongoing production processis notdisturbed. Thermographicinspection ofelectrical installations are used in three main areas:
Power generation
Power transmission
Power distribution, that is, industrial use of electrical energy.
The fact that these controls are carried out under normal operation conditions has created a natural division between these groups. The power generation companies measure during the periods of high load. These periods vary from country to country
7
Publ. No. 1557966 Rev. a155 – ENGLISH (EN) – February 6, 2006 17
Page 34
7 – Introduction to thermographic inspections of electrical installations
and for the climatic zones. The measurement periods may also differ depending on the type of plant to be inspected, whether they are hydroelectric, nuclear, coal-based or oil-based plants.
In the industry the inspections are—at least in Nordic countries with clear seasonal differences—carried out during spring or autumn or before longer stops in the oper­ation. Thus, repairs are made when the operation is stopped anyway. However, this seems to be the rule less and less, which has led to inspections of the plants under varying load and operating conditions.

7.2.2 General equipment data

The equipment to be inspected has a certain temperature behavior that should be known to the thermographer before the inspection takes place. In the case ofelectrical equipment, the physical principle of why faults show a different temperature pattern because of increased resistance or increased electrical current is well known.
However, it is useful to remember that, in some cases, for example solenoids, ‘over­heating’ is natural and does not correspond to a developing defect. In other cases, like the connections in electrical motors, the overheating might depend on the fact
7
that the healthy part is taking the entire load and therefore becomes overheated. A similar example is shown in section 7.5.7 – Overheating in one part as a result of a fault in another on page 33.
Defective parts of electrical equipment can therefore both indicate overheating and be cooler than the normal ‘healthy’ components. It is necessary to be aware of what to expect by getting as much information as possible about the equipment before it is inspected.
The general rule is, however, that a hot spot is caused by a probable defect. The temperature and the load of that specific component at the moment of inspection will give an indication of how serious the fault is and can become in other conditions.
Correct assessment in each specific case demands detailed information about the thermal behavior of the components, that is, we need to know the maximum allowed temperature of the materials involved and the role the component plays in the system.
Cable insulations, for example, lose their insulation properties above a certain tem­perature, which increases the risk of fire.
In the case of breakers, where the temperature is too high, parts can melt and make it impossible to open the breaker, thereby destroying its functionality.

7 – Introduction to thermographic inspections of electrical installations
The more the IR camera operator knows about the equipment that he or she is about to inspect, the higher the quality of the inspection. But it is virtually impossible for an IR thermographerto havedetailed knowledgeabout allthe differenttypes of equipment that can be controlled. It is therefore common practice that a person responsible for the equipment is present during the inspection.

7.2.3 Inspection

The preparationof theinspection shouldinclude thechoice ofthe righttype ofreport. It isoften necessaryto use complementary equipmentsuch as ampere meters in order to measure the current in the circuits where defects were found. An anemometer is necessary if you want to measure the wind speed at inspection of outdoorequipment.
Automatic functions help the IR operator to visualize an IR image of the components with the right contrast to allow easy identification of a fault or a hot spot. It is almost impossible to miss a hot spot on a scanned component. A measurement function will also automatically display the hottest spot within an area in the image or the difference between the maximum temperature in the chosen area and a reference, which can be chosen by the operator, for example the ambient temperature.
10712703;a3
7
Figure 7.1 An infrared and a visual image of a power line isolator
When the fault is clearly identified and the IR thermographer has made sure that it is not a reflection or a naturally occurring hot spot, the collection of the data starts, which will allow the correct reporting of the fault. The emissivity, the identification of the component, and the actual working conditions, together with the measured tempera­ture, will be used in the report. In order to make it easy to identify the component a visual photo of the defect is often taken.

7.2.4 Classification & reporting

Reporting has traditionally been the most time-consuming part of the IR survey. A one-day inspection could result in one or two days’ work to report and classify the found defects. This is still the case for many thermographers, who have chosen not to use the advantages that computers and modern reporting software have brought to IR condition monitoring.
Publ. No. 1557966 Rev. a155 – ENGLISH (EN) – February 6, 2006 19
Page 36
7 – Introduction to thermographic inspections of electrical installations
The classification of the defects gives a more detailed meaning that not only takes into account the situation at the time of inspection (which is certainly of great impor­tance), but also the possibility to normalize the over-temperature to standard load and ambient temperature conditions.
An over-temperature of +30°C (+86°F) is certainly a significant fault. But if that over­temperature is valid for one component working at 100% load and for another at 50% load, it is obvious that the latter will reach a much higher temperature should its load increase from 50% to 100%. Such a standard can be chosen by the plant’s circum­stances. Very often, however, temperatures are predicted for 100% load. A standard makes it easier to compare the faults over time and thus to make a more complete classification.

7.2.5 Priority

Based on the classification of the defects, the maintenance manager gives the defects a repair priority. Very often, the information gathered during the infrared survey is put together withcomplementary informationon the equipment collected by other means such as vibration monitoring, ultrasound or the preventive maintenance scheduled.
7
Even if the IR inspection is quickly becoming the most used method of collecting in­formation about electrical components safely with the equipment under normal oper­ating conditions, there are many other sources of information the maintenance or the production manager has to consider.
The priority of repair should therefore not be a task for the IR camera operator in the normal case. If a critical situation is detected during the inspection or during the classification of the defects, the attention of the maintenance manager should of course be drawn to it, but the responsibility for determining the urgency of the repair should be his.

7.2.6 Repair

To repair the known defects is the most important function of preventive maintenance. However, to assure production at the right time or at the right cost can also be impor­tant goals for a maintenance group. The information provided by the infrared survey can be used to improve the repair efficiency as well as to reach the other goals with a calculated risk.
To monitor the temperature of a known defect that can not be repaired immediately for instance because spare parts are not available, can often pay for the cost of in­spection a thousandfold and sometimes even for the IR camera. To decide not to repair knowndefects tosave on maintenance costs and avoid unnecessary downtime is also another way of using the information from the IR survey in a productive way.
20 Publ. No. 1557966 Rev. a155 – ENGLISH (EN) – February 6, 2006
Page 37
7 – Introduction to thermographic inspections of electrical installations
However, themost commonresult of the identification and classification of the detected faults is a recommendation to repair immediately or as soon as it is practically possible. It is important that the repair crew is aware of the physical principles for the identifica­tion of defects. If a defect shows a high temperature and is in a critical situation, it is very common that the repair personnel expect to find a highly corroded component. It should also come as no surprise to the repair crew that a connection, which is usually healthy, can give the same high temperatures as a corrodedone if it has come loose. These misinterpretations are quite common and risk putting in doubt the relia­bility of the infrared survey.

7.2.7 Control

A repaired component should be controlled as soon as possible after the repair. It is not efficient to wait for the next scheduled IRsurvey in order to combine a new inspec­tion with the control of the repaired defects. The statistics on the effect of the repair show that up to a third of the repaired defects still show overheating. Thatis the same as saying that those defects present a potential risk of failure.
To wait until the next scheduled IR survey represents an unnecessary risk for the plant.
Besides increasing the efficiency of the maintenance cycle (measured in terms of lower risk for the plant) the immediate control of the repair work brings other advan­tages to the performance of the repair crew itself.
7
When a defect still shows overheating after the repair, the determination of the cause of overheating improves the repair procedure, helps choose the best component suppliers and detect design shortcomings on the electrical installation. The crew rapidly sees the effect of the work and can learn quickly both from successful repairs and from mistakes.
Another reason to provide the repair crew with an IR instrument is that many of the defects detected during the IR survey are of low gravity. Instead of repairing them, which consumes maintenance and production time, it can be decided to keep these defects under control. Therefore the maintenance personnel should have access to their own IR equipment.
It is common to note on the report form the type of fault observed during the repair as well as the action taken. These observations make an important source of experi­ence that can be used to reduce stock, choose the best suppliers or to train new maintenance personnel.

7.3 Measurement technique for thermographic inspection of electrical installations

7.3.1 How to correctly set the equipment

A thermal image may show high temperature variations:
10712803;a4
Figure 7.2 Temperature variations in a fusebox
In the images above, the fuse to the right has a maximum temperature of +61°C (+142°F), whereas the one to the left is maximum +32°C (+90°F) and the one in the middle somewhere in between. The three images are different inasmuch as the tem­perature scale enhances only one fuse in each image. However, it is the same image and all the information about all three fuses is there. It is only a matter of setting the
7
temperature scale values.

7.3.2 Temperature measurement

Some cameras today can automatically find the highest temperature in the image. The image below shows how it looks to the operator.
10712903;a3
Figure 7.3 An infrared image of a fusebox where the maximum temperature is displayed
The maximum temperature in the area is +62.2°C (+144.0°F). The spot meter shows the exact location of the hot spot. The image can easily be stored in the camera memory.
The correct temperature measurement depends, however, not only on the function of the evaluation software or the camera. It may happen that the actual fault is, for example, a connection, which is hidden from the camera in the position it happens
22 Publ. No. 1557966 Rev. a155 – ENGLISH (EN) – February 6, 2006
Page 39
7 – Introduction to thermographic inspections of electrical installations
to be in for the moment. It might be so that you measure heat, which has been con­ducted oversome distance,whereas the ‘real’ hot spot is hidden from you. An example is shown in the image below.
10717603;a3
Figure 7.4 A hidden hot spot inside a box
Try to choose different angles and make sure that the hot area is seen in its full size, that is, that it is not disappearing behind something that might hide the hottest spot. In this image, the hottest spot of what the camera can‘see’, is +83°C (+181°F), where the operating temperature on the cables below the box is +60°C (+140°F). However, the real hot spot is most probably hidden inside the box, see the in yellow encircled area. This fault is reported as a +23.0°C (+41.4°F) excess temperature, but the real problem is probably essentially hotter.
7
Another reason for underestimating the temperature of an object is bad focusing. It is very important that the hot spot found is in focus. See the example below.
10717403;a2
Figure 7.5 LEFT: A hot spot in focus; RIGHT: A hot spot out of focus
In the left image, the lamp is in focus. Its average temperature is +64°C (+147°F). In the right image, the lamp is out of focus, which will result in only +51°C (+124°F) as the maximum temperature.

7 – Introduction to thermographic inspections of electrical installations

7.3.3 Comparative measurement

For thermographic inspections of electrical installations a special method is used, which is based on comparison of different objects, so-called measurement with a reference. This simply means that you compare the three phases with each other. This method needs systematic scanning of the three phases in parallel in order to assess whether a point differs from the normal temperature pattern.
A normal temperature pattern means that current carrying components have a given operation temperature shown in a certain color (or gray tone) on the display, which is usually identical for all three phases under symmetrical load. Minor differences in the color might occur in the current path, for example, at the junction of two different materials, at increasing or decreasing conductor areas or on circuit breakers where the current path is encapsulated.
The image below shows three fuses, thetemperatures of which are very close toeach other. The inserted isotherm actually shows less than +2°C (+3.6°F) temperature difference between the phases.
Different colors are usually the result if the phases are carrying an unsymmetrical
7
load. This difference in colors does not represent any overheating since this does not occur locally but is spread along the whole phase.
10713203;a3
Figure 7.6 An isotherm in an infrared image of a fusebox
A ‘real’ hot spot, on the other hand, shows a rising temperature as you look closer to the source of the heat. See the image below, where the profile (line) shows a steadily increasing temperature up to about +93°C (+199°F) at the hot spot.

7.3.4 Normal operating temperature

Temperature measurement with thermography usually gives the absolute temperature of the object. In order to correctly assess whether the component is too hot, it is necessary to know its operating temperature, that is, its normal temperature if we consider the load and the temperature of its environment.
As the direct measurement will give the absolute temperature—which must be con­sidered as well (as most components have an upper limit to their absolute tempera­tures)—it is necessary to calculate the expected operating temperature given the load and the ambient temperature. Consider the following definitions:
Operating temperature: the absolute temperature of the component. It depends
on the current load and the ambient temperature. It is always higher than the am­bient temperature.
Excess temperature (overheating): the temperature difference between a properly
working component and a faulty one.
7
The excess temperature is found as the difference between the temperature of a ‘normal’ component and the temperature of its neighbor. It is important to compare the same points on the different phases with each other.
As an example, see the following images taken from indoor equipment:
10713403;a4
Figure 7.8 An infrared image of indoor electrical equipment (1)
Publ. No. 1557966 Rev. a155 – ENGLISH (EN) – February 6, 2006 25
Page 42
7 – Introduction to thermographic inspections of electrical installations
10713503;a4
Figure 7.9 An infrared image of indoor electrical equipment (2)
The two left phases are considered as normal, whereas the right phase shows a very clear excess temperature. Actually, the operating temperature of the left phase is +68°C (+154°F), that is, quite a substantial temperature, whereas the faulty phase to the right shows a temperature of +86°C (+187°F). This means an excess temper­ature of +18°C (+33°F), that is, a fault that has to be attended to quickly.
For practical reasons, the (normal, expected) operating temperature of a component is taken as the temperature of the components in at least two out of three phases,
7
provided that you consider them to be working normally.. The ‘most normal’ case is of course that all three phases have the same or atleast almost the same temperature. The operating temperature of outdoor components in substations or power lines is usually only 1°C or 2°C above the air temperature (1.8°F or 3.6°F). In indoor substa­tions, the operating temperatures vary a lot more.
This fact is clearly shown by the bottom image as well. Here the left phase is the one, which shows an excess temperature. The operating temperature, taken from the two ‘cold’ phases, is +66°C (+151°F). The faulty phase shows a temperature of +127°C (+261°F), which has to be attended to without delay.

7.3.5 Classification of faults

Once a faulty connection is detected, corrective measures may be necessary—or may not be necessary for the time being. In order to recommend the most appropriate action the following criteria should be evaluated:
Load during the measurement
Even or varying load
Position of the faulty part in the electrical installation
Expected future load situation
Is the excess temperature measured directlyon thefaulty spot or indirectly through
conducted heat caused by some fault inside the apparatus?
Excess temperatures measured directly on the faulty part are usually divided into three categories relating to 100% of the maximum load.

7.4 Reporting

Nowadays, thermographicinspections of electrical installationsare probably, without exception, documentedand reportedby theuse ofa reportprogram. Theseprograms, which differ from one manufacturer to another, are usually directly adapted to the cameras and will thus make reporting very quick and easy.
The program, which has been used for creating the report page shown below, is called ThermaCAM™Reporter. It isadapted toseveral typesof infrared cameras from FLIR Systems.
A professional report is often divided into two sections:
Front pages, with facts about the inspection, such as:
Who the client is, for example, customer’s company name and contact person
Location of the inspection: site address, city, and so on
Date of inspection
Date of report
Name of thermographer
7
Signature of thermographer
Summary or table of contents
Inspection pages containing IR images to document and analyze thermal properties
or anomalies.
Identification of the inspected object:
What is the object: designation, name, number, and so on
Photo
IR image. When collecting IR images there are some details to consider:
Optical focus
Thermal adjustment of the scene or the problem (level & span)
Composition: proper observation distance and viewing angle.
Comment
Is there an anomaly or not?
Is there a reflection or not?
Use a measurement tool—spot, area or isotherm—to quantify the problem.
Use the simplest tool possible; a profile graph is almost never needed in electrical reports.

7.5 Different types of hot spots in electrical installations

7.5.1 Reflections

The thermographiccamera sees any radiation that enters the lens, not only originating from the object that you are looking at, but also radiation that comes from other sources andhas beenreflected by the target. Most of the time, electrical components are like mirrors to the infrared radiation, even if it is not obvious to the eye. Bare metal parts are particularly shiny, whereas painted, plastic or rubber insulated parts are mostly not. In the image below, you can clearly see a reflection from the thermo­grapher. This is of course not a hot spot on the object. A good way to find out if what you see is a reflection or not, is for you to move. Look at the target from a different angle and watch the ‘hot spot.’ If it moves when you do, it is a reflection.
Measuring temperature of mirror like details is not possible. The object in the images below has painted areas which are well suited for temperature measurement. The material is copper, which is a very good heat conductor. This means that temperature variation over the surface is small.
10717503;a2

Figure 7.11 Reflections in an object

7.5.2 Solar heating

The surface of a component with a high emissivity, for example, a breaker, can on a hot summer day be heated up to quite considerable temperatures by irradiation from the sun. The image shows a circuit breaker, which has been heated by the sun.

Eddy currents can cause a hot spot in the current path. In cases of very high currents and close proximity of other metals, this has in some cases caused serious fires. This type of heating occurs in magnetic material around the current path, such as metallic bottom plates for bushing insulators. In the image above, there arestabilizing weights, through which a high current is running. These metal weights, which are made of a slightly magnetic material, will not conduct any current but are exposed to the alter­nating magnetic fields, which will eventually heat up the weight. The overheating in the image is less than +5°C (+9°F). This, however, need not necessarily always be the case.

7.5.4 Load variations

3-phase systems are the norm in electric utilities. When looking foroverheated places, it is easy to compare the three phases directly with each other, for example, cables, breakers, insulators. An even load per phase should result in a uniform temperature pattern forall threephases. Afault maybe suspectedin caseswhere the temperature of onephase differs considerably from the remaining two. However, you should always make sure that the load is indeed evenly distributed. Looking at fixed ampere meters or using a clip-on ampere meter (up to 600 A) will tell you.

Figure 7.14 Examples of infrared images of load variations
The image to the left shows three cables next to each other. They are so far apart that they can be regarded as thermally insulated from each other. The one in the middle is colder than the others. Unless two phases arefaulty and overheated, this is a typical example of a very unsymmetrical load. The temperature spreads evenly along the cables, which indicates a load-dependent temperature increase rather than a faulty connection.
The image to the right shows two bundles with very different loads. In fact, the bundle
7
to the right carries next to no load. Those which carry a considerable current load, are about 5°C (9°F) hotter than those which do not. No fault to be reported in these examples.

7.5.5 Varying cooling conditions

10714103;a3
Figure 7.15 An infrared image of bundled cables
When, for example, a number of cables are bundled together it can happen that the resulting poorcooling of the cables in the middle can lead to them reaching very high temperatures. See the image above.
The cables to the right in the image do not show any overheating close to the bolts. In the vertical part of the bundle, however, the cables are held together very tightly, the cooling of the cables is poor, the convection can not take the heat away, and the cables arenotably hotter, actually about 5°C (9°F) above the temperature ofthe better cooled part of the cables.

7.5.6 Resistance variations

Overheating can have many origins. Some common reasons are described below. Low contact pressure can occur when mounting a joint, or through wear of the mate-
rial, for example, decreasing spring tension, worn threads in nuts and bolts, even too much force applied at mounting. With increasing loads and temperatures, the yield point of the material is exceeded and the tension weakens.
The image to the left below shows a bad contact due to a loose bolt. Since the bad contact is of very limited dimensions, it causes overheating only in a very small spot from which the heat is spread evenly along the connecting cable. Note the lower emissivity ofthe screw itself, whichmakes it look slightly colder than the insulated—and thereby it has a high emissivity—cable insulation.
The image to the right shows another overheating situation, this time again due to a loose connection. It is an outdoor connection, hence it is exposed to the cooling effect of the wind and it is likely that the overheating wouldhave showna higher temperature, if mounted indoors.

connection, exposed to the wind cooling effect.

7.5.7 Overheating in one part as a result of a fault in another

Sometimes, overheating can appear in a component although that component is OK. The reason is that two conductors share the load. One of the conductors has an in­creased resistance, but the other is OK. Thus, the faulty component carries a lower load, whereas the fresh one has to take a higher load, which may be too high and which causes the increased temperature. See the image.

7.6 Disturbance factors at thermographic inspection of electrical installations

During thermographic inspections of different types of electrical installations, distur­bance factors such as wind, distance to object, rain or snow often influence the measurement result.

7.6.1 Wind

During outdoorinspection, the cooling effect of the wind should be taken intoaccount. An overheating measured at a wind velocity of 5 m/s (10 knots) will be approximately twice as high at 1 m/s (2 knots). An excess temperature measured at 8 m/s (16 knots) will be 2.5 times as high at 1 m/s (2 knots). This correction factor, which is based on empirical measurements, is usually applicable up to 8 m/s (16 knots).
There are, however, cases when you have to inspect even if the wind is stronger than 8 m/s (16 knots). There are many windy places in the world, islands, mountains, and so on but it is important to know that overheated components found would have shown a considerably higher temperature at a lower wind speed. The empirical cor­rection factor can be listed.
Correction factorWind speed (knots)Wind speed (m/s)

1.6463
1.8684
2.06105
2.23126
2.40147
2.54168
The measured overheating multiplied by the correction factor gives the excess tem­perature with no wind, that is, at 1 m/s (2 knots).

7.6.2 Rain and snow

Rain and snow also have a cooling effect on electrical equipment. Thermographic measurement can still be conducted with satisfactory results during light snowfall with dry snow and light drizzle, respectively. The image qualitywill deteriorate in heavy

7 – Introduction to thermographic inspections of electrical installations
snow or rain and reliable measurement is no longer possible. This is mainly because a heavy snowfall as well as heavy rain is impenetrable to infrared radiation and it is rather the temperature of the snowflakes or raindrops that will be measured.

7.6.3 Distance to object

This image is taken from a helicopter 20 meters (66 ft.) away from this faulty connec­tion. The distance was incorrectly set to 1 meter (3 ft.) and the temperature was measured to+37.9°C (+100.2°F).The measurementvalue afterchanging the distance to 20 meters (66 ft.), which was done afterwards, is shown in the image to the right, where the corrected temperature is +38.8°C (+101.8°F). The difference is not too crucial, but may take the fault into a higher class of seriousness. So the distance setting must definitely not be neglected.

The measured average temperatures are, from left to right, +85.3°C (+185.5°F),+85.3°C (+185.5°F), +84.8°C (+184.6°F), +84.8°C (+184.6°F), +84.8°C (+184.6°F) and +84.3°C (+183.7°F) from a blackbody at +85°C (+185°F). The ther­mograms are taken with a 12° lens. The distances are 1, 2, 3, 4, 5 and 10 meters (3, 7, 10, 13, 16 and 33 ft.). The correction for the distance has been meticulously set and works, because the object is big enough for correct measurement.

7.6.4 Object size

The second series of images below shows the same but with the normal 24° lens. Here, the measured average temperatures of the blackbody at +85°C (+185°F) are: +84.2°C (+183.6°F), +83.7°C (+182.7°F), +83.3°C (+181.9°F), +83.3°C(+181.9°F), +83.4°C (+181.1°F) and +78.4°C (+173.1°F).
The last value, (+78.4°C (+173.1°F)), is the maximum temperature as it was not possible to place a circle inside the now very small blackbody image. Obviously, it is not possible to measure correct values if the object is too small. Distance was properly set to 10 meters (33 ft.).
10714603;a3
7
Figure 7.20 Temperature readings from ablackbody at +85°C (+185°F) atincreasing distances (24° lens)
The reason for this effect is that there is a smallest object size, which gives correct temperature measurement. This smallest size is indicated to the user in all FLIR Sys­tems cameras. The image below shows what you see in the viewfinder of camera model 695. The spot meter has an opening in its middle,more easily seen in the detail to the right. The size of the object hasto be bigger than that opening or some radiation from its closest neighbors, which are much colder, will come into the measurement as well, strongly lowering the reading. In the above case, where we have a point­shaped object, which is much hotter than the surroundings, the temperature reading will be too low.

7.7 Practical advice for the thermographer

Working in a practical way with a camera, you will discover small things that make your job easier. Here are ten of them to start with.

7.7.1 From cold to hot

You have been out with the camera at +5°C (+41°F). To continue your work, you now have to perform the inspection indoors. If you wear glasses, you are used to having towipe offcondensed water, or you will not be able to see anything. The same thing happens with the camera. To measure correctly, you should wait until the camera has become warm enough for the condensation to evaporate. This will also allow for the internal temperature compensation system to adjust to the changed condition.

7.7.2 Rain showers

If it starts raining you should not perform the inspection because the water will drasti­cally change the surface temperature of the object that you are measuring. Neverthe­less, sometimes you need to use the camera even under rain showers or splashes. Protect your camera with a simple transparent polyethylene plastic bag. Correction for the attenuation which is caused by the plastic bag can be made by adjusting the object distance until the temperature reading is the same as without the plastic cover. Some camera models have a separate External optics transmission entry.
7

7.7.3 Emissivity

You have to determine the emissivity for the material, which you are measuring. Mostly, you will not find the value in tables. Use optical black paint, that is, Nextel Black Velvet. Paint a small piece of the material you are working with. The emissivity of the optical paint is normally 0.94. Remember that the object has to have a temper­ature, which is different—usually higher—than the ambient temperature. The larger the difference the better the accuracy in the emissivity calculation. The difference should be at least 20°C (36°F). Remember that there are other paints that support very high temperatures up to +800°C (+1472°F). The emissivity may, however, be lower than that of optical black.
Sometimes you can not paint the object that you are measuring. In this case you can use a tape. A thin tape for which you have previously determined the emissivity will work in most cases and you can remove it afterwards without damaging the object of your study. Pay attention to the fact that some tapes are semi-transparent and thus are not very good for this purpose. One of the best tapes for this purpose is Scotch electrical tape for outdoor and sub-zero conditions.

7.7.4 Reflected apparent temperature

You are in a measurement situation where thereare several hot sources that influence your measurement. You need to have the right value for the reflected apparent tem­perature to input into the camera and thus get the best possible correction. Do it in this way: set the emissivity to 1.0. Adjust the camera lens to near focus and, looking in the opposite direction away from the object, save one image. With the area or the isotherm, determine the most probable value of the average of the image and use that value for your input of reflected apparent temperature.

7.7.5 Object too far away

Are you in doubt that the camera you have is measuring correctly at the actual dis­tance? A rule of thumb for your lens is to multiply the IFOV by 3. (IFOV is the detail of the object seen by one single element of the detector). Example: 25 degrees cor­respond to about 437 mrad. If your camera has a 120 × 120 pixel image, IFOV be­comes 437/120 = 3.6 mrad (3.6 mm/m) and your spot size ratio is about 1000/(3 × 3.6)=92:1. This means that at a distance of 9.2 meters(30.2 ft.), your target has to be at least about 0.1 meter or 100 mm wide (3.9"). Try to work on the safe side by coming closer than 9 meters (30 ft.). At 7–8 meters (23–26 ft.), your measurement
7
should be correct.

8.4 Working with alarms

You can choose between the following alarm outputs:
a silent alarm, which, willmake thebackground of the corresponding measurement
function turn red when an alarm is triggered
an audible alarm, which, compared to the silent alarm, also triggers a ’beep’
A settings can also be made in the camera so that an alarm output takes into account the referencetemperature. A typical application when you would want to use an alarm that takes into account the reference temperature is screening of people for face temperature detection.
Firstly, the reference temperature is set by screening 10 persons with normal face temperature. The camera puts each of these 10 results in an internal camera buffer and calculates the average temperature value after having discarded the two highest and two lowest values in the event of erroneous samples. Every time a new sample is saved to the internal buffer, the oldest sample will be discarded and a new reference temperature will be calculated ’on the fly’.
Using an alarm that takes into account the reference temperature means that an alarm output will only be triggered if the temperature value exceeds the sum of the average temperature value in the buffer + the user-defined delta alarm offset value.

However, the camera software prioritizes files that are stored at directory level and the directory has to be selected in order to store the emissivity file in the camera memory. If the camera software does not find an emissivity file at directory level, it searches for similar files at root level and saves those instead.
You can set T Reflected if Local is enabled. If not, this option will be shaded.
