What type of information should be included in an electrical thermographic report ?

This is something that varies from one company to another, and indeed from one person to another. There is no real standard report that can be used universally. The following are only suggestions, and my opinion, it is also not intended to be a complete list.

Cover page

This normally contains the details of the company carrying out the survey and some customer details. Other information like the address of the customer and the survey date can be included.

General information page

This normally contains things like an executive summary, the reason for the survey and details about the site and the people on the site.

Summary table page

This is a very important page to include in any report. It typically includes a summary table, with a list of the problems found, along with the associated locations and fault ratings (if used). The reason this is important is that reports are often sent to managers and this is the page they usually read first. They look at the summary table to see where the problems are located, they will use this information to decide if they need to read further, and to decide on possible corrective action.

Fault page

This is usually a single fault per page, and it should include an infrared image of the fault, a photo of the fault, the location of the fault, a description of the equipment, a description of the fault, the severity rating and recommended action.

Other pages

Calibration certificate, if a camera is calibrated the report should include a copy of the certificate. Normally when one has not been included the camera is out of calibration.

Thermographer’s qualification. Again, if the thermographer is certified then he would normally include a copy of his certificate, or at least details about it. Dont just look at the certification level, look also at what type of certification it is. The most preferable is certification by a third party certification body, not his own company or a training company. Generally people that are certified to independently a high level want to let people know, and will include copies of their certificates.


  • Dear All,
    Recently i did a thermal inspection by Camera and i wanna know how shall i judge and interpret the results
    in addition i ask if this interpretations are also applicable to both of low and high voltage.


  • The correct interpretation of thermal images comes from a combination of training/certification, experience and the understanding of the object/conditions in question. This cannot be thought correctly in response to a blogpost. There are various subjects relevant to the overall interpretation, and you would need to be well grounded in all of these. The camera quality also bears a big part in this, as does your ability to use it correctly.

    I recommend, attending a certified Level 1 course, and purchasing a copy of ISO 18436 and ISO 18434.
