A typical plant is full of equipment that requires periodic infrared (IR) inspection. The challenge, as any thermographer knows, is getting an accurate indication of equipment health. Properly compensating for the various emissivity values of all the components one encounters on the factory floor is possibly the most critical factor in performing accurate and meaningful inspections. Even slight errors in emissivity compensation can lead to significant errors in temperature and Delta T (difference in temperature) calculations. Electrical cabinets are a good example, as they may contain materials with emissivity values ranging from 0.07 to 0.95.

For some components, it can be difficult to determine the correct emissivity value. In the case of a highly polished component like a bus bar, the actual emissivity may be so low as to make temperature measurement impractical. It is strongly recommended that thermographers understand the surface of the primary targets. Once identified, those surfaces should be treated with a high-emissivity covering so that all targets have a standardized emissivity. Thermographers can apply electrical tape, high-temperature paint (such as grill paint), or high-emissivity labels (like the IR-ID labels from IRISS). When all targets have a standard emissivity, refection issues are minimized and measurement errors from reflected ambient energy are greatly reduced. High-emissivity targets of varying shapes can also provide a useful point-of-reference both for the thermographer and the technician making repairs.

1.    Emissivity is one of the most important variables a thermographer must understand.
2.    Whenever possible, know the emissivity of your target and compensate for it using the emissivity setting on the camera.
3.    Incorrect emissivity settings can have a significant effect on the accuracy of qualitative and quantitative data (thermograms and temperature calculations).
4.    Using an emissivity value that is higher than the actual emissivity of the target will result in electrical faults appearing cooler than they actually are.
5.    Emissivity errors are not linear, but are exponential in nature (Stephan-Boltzmann’s Law). The exponential nature of the error also means that ?T values (differences in temperature) can be greatly affected by the errors as well.
6.    When installing IR windows it is important to standardize the emissivity of the targets while the switch-gear is open (and de-energized).
7.    Common treatments for target surfaces are: grill paint, electrical tape and IRISS IR-ID labels.

To make your job easier during your next electrical inspection, take a look at IRISS IR-ID Labels. Regardless of experience and skill level, thermographers will improve efficiency with IR-ID Labels since any fault diagnosis is only as reliable as the data collected.


Many people are not aware that the detector in an infrared camera actually only reads electromagnetic radiation it receives in a specific range of wavelengths. In order to display this in a useful reading the camera makes several calculations in order to convert the actual data to a temperature. The emissivity and transmissivity (sometimes depending on the camera manufacturer) have to be manually entered into the camera’s menuif this value is entered incorrectly the actual temperature will be exponentially different (see Stefan-Boltzmann’s Law) than the displayed temperature. The old saying of “well as long as it is consistently wrong the change will be noted” is not entirely correct either, as the difference between phases will also be exponentially wrong. The error is going to be worse as the temperature rises – if the differential between the measured temperatures is significant then the displayed temperatures could be significantly different!

So that phase imbalance that looks like it is only a couple of degrees different could actually be upwards of 30 degrees! The visual setup of the camera could be the only other way of determining the severity of a potential defect. As anyone who has spent some time looking through a camera will tell you the visual component can be significantly altered (both to make things look better than they are as well as to show “elevated” differentials.) Depending on the level, span and range setup on the camera it would be very easy to miss a severe problem.


With this in mind it is easy to see why there are so many infrared problems that aren’t caught. In order to ensure that our customers “See What You’ve Been Missing”, all IRISS polymer based windows utilize the same grade and thickness of polymer, so that if you have correctly setup your camera for one IRISS window you can know without any doubt that it is “calibrated” for all IRISS windows. Our Fixed And Stable Transmission (FAST) is exactly what the name implies – unchanging! The ambient temperature outside, length of time in the field, relative humidity or barometric pressure have no effect on transmission rate and therefore no effect on your readings!

An infrared (IR) inspection of electrical distribution systems are the same whether they are on a ship at sea, on a ship in port, or in a building. The main difference is that if a critical component fails within a building it can be replaced far more easily than if it was on a ship at sea…

This is why it is critical to make sure that the electrical systems in a ship are in A1 condition before the ship leaves port. It is imperative to inspect these systems regularly at sea during their day-to-day operations to find and rectify any developing faults before a breakdown occurs.

Because of this critical demand, IRISS has strived to fill that need. As such IRISS has become the only company to hold the DNV certification awarded for Marine and Offshore Applications. This allows preventative maintenance on electrical equipment in vertical markets covering rules for ships, cruise liners, tankers, and offshore oil rigs.


Electrical systems are amongst the most critical areas on board ship.

An important consideration while completing IR inspections at sea is that a ship pitches and rolls and as such is not a stable platform from which to work. This is an extremely hazardous environment and full precautions must be taken. Electrical cabinets should not be opened when energized. IRISS IR windows are recommended to ensure stability of your electrical installations, safety of personnel and effective thermographic inspections on fully energized equipment.

The main restriction to any IR inspection is safe access to the energized components that you wish to inspect. IRISS IR windows are the most robust systems available on the market today. They are the first IR windows in the world to be awarded Lloyds Type approval and ABS (American Bureau of Shipping) certificates. They are the only IR lens assembly able to pass the impact, load and flammability standards specified in IEEE and UL.

Our patented IR lens assemblies are waterproof, resistant to light acids and alkalis, and are unaffected by long term vibration or high frequency noise, thus making IRISS IR windows the idyllic product in its class available for the marine industry today.

IRISS recently announced impressive testing results stemming from three of their products, the VPT and two of their new CAP-ENV IR Windows. (read the press release here).

IRISS’ VPT-100, CAP-ENV-6 and CAP-ENV-12 went under intense testing. The Arc flash test was performed in Poland, and the results were just down right impressive, the IR Windows were Arc Flash tested in line with the requirements of IEC62271-200 (1KV -50KV metal enclosed switchgear) at 6KV, 31.7kA, for 1.1 seconds, (was twice as long as standard tests).  All the IRISS products successfully passed this extreme test.

Unlike Crystal Based IR windows the IRISS VPT and CAP-ENV Systems are the only visual and IR windows that are Impact resistant, maintain a fixed and stable IR transmission and offer the largest FOV (field of view) of any IR window available today.  The IRISS’ VPT and CAP-ENV Series are by far the strongest most durable IR Window systems available on the market today.

IRISS Electrical Maintenance Safety Devices are used in a multitude of industries such as, Power Generation, Manufacturing, Data Centers, Maritime and switchgear OEMs.  IRISS is continuously improving infrared window systems and developing innovative concepts in the electrical maintenance safety device market.  This has led to the creation of the CAP-ENV System, an innovative industrial IR window that could withstand harsh environmental conditions, offering a durable transparent polymer lens that allows visual, UV, and infrared IR inspections to be completed whilst the panel remains in an enclosed and guarded condition.  More information can be found at
