Thermovision Thermography

The physiology of the human eye allows the registration of electromagnetic waves in the field of so-called visible light. It allows us to see the surroundings. This range, referred to as the visible spectrum in physics, is multicolored, made up of a whole range of colors that we can see on a daily basis.

However, the perception of objects is not identical for all creatures on Earth. For example, insects see the world in the narrowed range of the white spectrum, corresponding to the colors of shades of yellow and blue and additionally in the range of ultraviolet wavelengths. It is closely related to the morphology of insect plants, whose specific parts absorb ultraviolet radiation, creating a range of colors that are attractive to these creatures. In turn, most species of snakes had the ability to see infrared waves, which significantly helps them to locate, even in conditions of limited visibility or at night, warmer than the surroundings of the victim.

Subjugation of infrared waves can now boast of people using for this apparatus based on the broadly understood thermovision technique. Begun in the 1950s, with the appearance of the first thermal-cooled thermal imaging camera for military purposes, this technique has evolved to the point that thermovision devices have become part of the market for rapidly developing non-invasive measurement methods.

Implementation of energy-saving solutions in commercial real estates, commercial establishments and industrial plants has become a necessity in the era of modern management. The lack of an effective austerity policy in this respect leads to a decrease in the profitability of the business entity, and thus to a gradual loss of competitive advantage and market shares.

Thermal imaging in construction has become one of the most popular methods for quick and non-invasive analysis of the thermal condition of buildings (including industrial cold stores). Thermovision can be an independent service or be the starting point for further analysis – energy audit, renovation work or business negotiations with the owner, insurer or property manager. Selected applications of thermovision in the construction sector are presented below.

Thermomodernization – in order to determine the nature and priority of thermo-modernization works, the task of which is to reduce the thermal energy consumption of the building.

Anomalies – both thermal (cooling down of rooms) and humidity (condensation of water vapor, fungus), caused by errors at the design stage (design flaws), performances (manufacturing defects, usually hidden) or inappropriate use of real estate. Thermovision allows to determine the cause of their occurrence, indicate the party responsible for their creation and removal, and present possible variants of repair.

Energy efficiency – general control of the building, which has already undergone thermal modernization works, in terms of the quality of the thermal shield of the building, transport efficiency and heat accumulation (insulation of heating ducts, heat storage tanks) and location of possible thermal bridges and sources of energy losses.

Regular temperature control of key electrical devices in a production / industrial plant, office building, ship / vessel or other facility is currently the basic method of prediction of potential electrical failures. Thermovision techniques, due to the non-invasive nature of surveys, are among the most effective and the most economical methods of prevention in this area.

Thermography enables inspection of electrical components in their regular, uninterrupted work. But more importantly – allows you to locate those elements that show signs of initial, normal or critical overheating and plan service work in advance.

Electrotechnical thermography includes testing of switchgear cabinets, electrical switchgears, transformer stations, devices and electrical machines, cable lines and overhead, as well as busbars and other electrotechnical components that may be overheated and crash.

Infrared inspections in the electrical, electrotechnical and energy sectors, but also in the field of automation, are carried out at a specific frequency that is determined based on safety requirements, type of facility and installed equipment, as well as other criteria determined during the local vision and is usually from 3 to 6 months.
