If you are thinking about getting a thermography inspection for your property, you are bound to have some questions. We have tried to answer some of our clients’ most commonly asked questions in order to give you as much information as possible.
Please browse through our FAQs below or feel free to contact us if you have a question that’s not addressed. Our friendly team is here to help you find answers to all your questions.
Thermal imaging is a method of improving visibility of certain objects in dark environments by detecting the objects’ infrared radiation and creating an image based on that information.
Human vision can only detect a small part of the electromagnetic spectrum; a thermal camera can provide extra vision within this infrared spectrum. This can broaden the vision of objects viewed and will visualise the variations in thermal temperature of objects observed.
Every object emits an infrared energy (heat) as a function of their temperature. This infrared energy that’s emitted is know as its heat signature. Generally, the hotter an object is, the more radiation it emits.
A thermal imager (thermal camera) is essentially a heat sensor that is capable of detecting small differences in an object’s temperature. The device gathers the infrared radiation from objects in the scene and creates an electronic image based on information about the temperature differences.
A German physicist, Georg Simon Ohm discovered there is direct proportionality between the voltage applied across a conductor and the resultant electric-current, known now as “Ohm’s Law”.
He discovered that for a given current, as a component’s resistance increases it will dissipate more power and it’s temperature would inevitably rise.
Amplified resistance and heat are the main reasons most electrical components fail and infrared cameras detect this heat. Because most electrical things tend to get hot before they fail, infrared inspection is the preferred diagnostic technology used to detect early failures in electrical systems and switchgear.
After you have given us an inventory list of the equipment that you want scanned (we can assist you with this), we will arrange a time and date that suits you to have the inspection carried out.
During the inspection if we find any serious problems we will notify you immediately. After the inspection you will receive a comprehensive but easy-to-read report. This will be given as hard copies and emailed as a PDF.
The report will include:
- Information about IR scanning (including standards)
- Inspection summary
- Report summary
- List of equipment inspected
- Cost savings report
- List of exceptions found (possible problems)
- Full colour thermal images and photos
All of our reports are precise, easy to understand and available within 48 hours of the completed inspection. They give a quick and comprehensive assessment of the situation, allowing you to carry out any necessary action or repairs. We can also provide follow up inspections after repair work has been carried out.
At Thermographic Solutions, we use the most advanced thermal imaging devices from FLIR. We use a wide range of infrared cameras so that we can ensure we have the right equipment for your needs. You can read more about FLIR cameras here: FLIR
If you’re a business that uses any form of electrical equipment, like power tools for tradies or computers for office workers, then you need to regularly have it tested and tagged to ensure its safety.
There are many benefits associated with testing your electrical equipment against any faults and damages.
- Some of the more important benefits are:
- Improved safety for employees and third parties
- Reduced insurance premiums
- Minor repairs of equipment made onsite to minimise down time
- Lower repair costs
- Asset data management and tracking systems
- Minimised liability
- Increase profits
Thermal imaging not only provides increased safety but a good return on your investment. The cost of an inspection and a detailed report is a fraction of the cost of a potential failure.
When Thermographic Solutions undertake regular inspections, you may be eligible for lower premiums when it comes to insurance coverage. This is because there is a greater insight into a fire risk on your premises.
Any electrical or mechanical failure can incur probable injury or loss of life. Through Thermographic Solutions inspections and thermal imaging, the risk of this is decreased.
Australia is still yet to develop thermography standards; here at Thermographic Solutions we operate under internationally recognised standards.
We only use proven techniques during our inspection and assessment process and currently standards exist for the certification of personnel, operation of equipment, and inspections of electrical, mechanical, and structural systems.
The Definitive Internet Resource for Infrared Thermography provides a list of organisations that publish infrared standards, infrared specifications and infrared guidelines for performing infrared inspections and/or related testing. Discover them here (http://www.irinfo.org/infrared-standards-application-standards/)
The Non Destructive Testing Resource Centre have put together some background information and tips on how to interpret thermal images to give you a greater understanding of what is involved in thermal scans.
Some electrical conditions that can be detected by an inspection by Thermographic Solutions are:
- Loose/deteriorated connections
- Inductive heating
- Defective equipment
- Open circuits
- Unbalanced loads
A thermographic inspection can be either an interior or exterior survey. The energy auditor from Thermographic Solutions decides what method would give the best results under certain weather conditions.
Interior scans are the most common, as warm air escaping from a building doesn’t always move through the walls in a straight line. Heat loss detected in one area of the outside wall could originate at another location on the inside of the wall.
It is also harder to detect temperature differences on the outside surface of the building during windy weather. So interior surveys are generally more accurate because they benefit from reduced air movement.
The Australian police services have adapted this infrared technology to assist them in a number of ways to not only keep themselves safe on the job but to solve the most complex crimes.
Infrared technology can help police offers in staying safe by spotting suspects hiding. In fact infrared can spot someone hiding behind an object like a box or rubbish bin if they radiate enough heat to cast a thermal image around the object.
Thermal cameras can see people running in the dark and even through the cover of trees. These cameras can also identify a recently driven car (by the warmth of the hood), or in some cases even the warmth of the skid marks left by an escaping car.
Thermal imaging cameras are also used for evidence collection and the technology can help police officers spot an object a suspect has discarded while being pursued, or gather evidence or uncover circumstances where evidence tampering has occurred.
After implementing a search warrant, police can use these cameras to look for objects hidden in interior walls, like drugs and money. These objects act like insulation in the walls, and may produce a different thermal image in that section of the wall compared with the surrounding wall space and studs.
Fire fighters and rescue personnel also use thermal imaging. Many fire departments use hand-held or helmet-mounted cameras to see through smoke to find victims, or to see “hot spots” in walls before a fire spreads.
