IRT is a non-contact, non-destructive test method that utilises a thermal imager to detect, display and record thermal patterns and temperatures across the surface of an object. Since infrared radiation is emitted by all objects based on their temperatures, thermography makes it possible to "see" one's environment with or without visible illumination.
Why use IRT for predictive maintenance?
To keep businesses operational at all times, many have established predictive maintenance programs. One of the most valuable diagnostic tools for any predictive maintenance programme is IRT.
SK Electrical uses the latest infrared cameras for electrical Low Voltage inspections. As electrical connections become loose, there is a resistance to current that can cause an increase in temperature. This can then cause components to FAIL resulting in unplanned outages and injuries.
With the Fluke Ti50 IR FlexCam SK Electrical have the ability to save an IR image together with a visual image allows you to show that HOTSPOT or THERMAL ANOMALY in detail to the people who will be making the repairs.
Our cameras deliver crisp, high-resolution thermal images that will register temperature differences as small as 0.05°c
Why use IRT for the building industry?
IRT is a powerful and non-evasive technique used to monitor the condition of buildings. Detecting leaks in flat roofs is a common application, as water retains heat longer than the rest of the roofing material and can easily be detected with a Thermal Imaging system very late in the evening after the rest of the roof has been cooled down. Tremendous savings can be made by repairing wet areas, rather than replacing the entire roof.
Another use is the detection of AIR LEAKS by identifying the air change rate with the help of what is known as the BLOWER DOOR PROCESS. This process creates UNDER-PRESSURE in the building. Since the air pressure OUTSIDE the building is HIGHER than the pressure inside, air will try to ENTER through unsealed areas. Thanks to IRT there is no need to fill the room with smoke to visualise the AIRFLOW.
Once identified, leaking areas can easily be fixed before coverings and fittings make the elimination of this potential construction fault, an expensive and cumbersome process.
Thanks to thermography it is now easy to prove the competency and proficiency of BUILDING CONTRACTORS. It gives an instantaneous visualisation of the heat losses, the humidity and air leaks that can occur in buildings.
Other applications include:
The location of THERMAL BRIDGES, which indicates spots in a building where energy is being wasted.
A badly insulated ROOF is yet another construction failure for which WASTED ENERGY & MONEY can be instantly traced.
IRT also provides valuable information during the renovation of buildings
Hidden framework constructions, clearly become visible in the IR image.
WHATEVER THE PROBLEM our IR CAMERAS WILL MAKE THEM CLEARLY VISIBLE.
IRT is now being advocated for use in conjunction with the new HIPS and the Energy Performance Certificates that are associated with them.
Although currently starting in England and Wales IRT is being considered best practice throughout the industry.
Portable Appliance Testing is more accurately referred to as In-service Inspection and Testing of Electrical Equipment. The following provides guidance on the inspection and testing of electrical appliances, luminaries and information technology equipment supplied by a plug and socket and similar equipment.
Inspection and testing is reduced to three activities:
(1) user checks
(2) formal visual inspections (without tests)
(3) combined inspections and tests.
This website considers the obligations imposed on persons by
- the Health and Safety at Work etc. Act 1974
- the requirements of the Provision and Use of Work Equipment Regulations 1998
- the Management of Health and Safety at Work Regulations 1999
- the Workplace (Health, Safety and Welfare) Regulations 1992
- and the Electricity at Work Regulations 1989 (Northern Ireland, 1991)
The guidance relates to offices, shops, hotels, schools and general industrial locations. Where premises have mixed use, the most appropriate mix of frequencies of inspection and of testing will need to be adopted.
Periodic Testing & Inspection is necessary as all Electrical installations deteriorate with age. This is due to a number of factors such as damage, wear and tear, corrosion, excessive electrical loading and environmental influences.
Public safety does not end with the installation of a fire alarm or emergency lighting system! It is essential that regular inspections are performed ensuring that the requisite degree of sensitivity to fire and emergency lighting is maintained.
