Thermal Imaging Scan
Why Thermal Imaging?
Every object emits infrared radiation. The human eye cannot see this, as it is outside the wavelength which can be resolved by a naked eye. However, the central element of an infrared detector is sensitive to infrared radiation. It determines the temperature of the object's surface, and makes it visible for the human eye as an image. This process is referred to as thermography.
In order to make the infrared radiation visible, the detector records it and converts into electric signal giving each signal a certain colour which is then shown on display of the thermal imaging camera. In principle, thermal imaging camera translates wavelengths from the infrared spectrum into wavelengths which can be visible to the human eye.
Thermal Imaging or Thermography has a long history, although over the past fifty years, it uses has increased dramatically with the commercial and industrial applications. Maintenance technicians using thermography to locate overheating terminals and sections of electrical systems, to locate early signs of impending failures. Facility management professionals are using it for detection of heat leaks troth thermal insulation, doors, windows, gaps and construction materials, which is useful for improvement of efficiency heating and air-conditioning systems. Doctors are using thermography in diagnosis of human internal lesions. Firefighters are using this technology to see through the smoke in order to evaluate fire severity. There are may other areas where thermography is successfully utilized and they not limited just to industries, agriculture, medicine, risk management, rescue, military, maintenance, space, general safety and etc.
Thermal imaging is used for all kinds of safety checks to reduce the risk of fire or premature electrical and mechanical equipment failure. Thermal imaging inspectors can help find defective connections or 'hot joints' before they cause irreversible damage to equipment and buildings. They can also check for unbalanced phase supply in 3 phase electrical switchboards.
Overheated substations, transformers and other electrical components are presenting potential and real risk of electrical fires and blowouts, making the regular thermal imaging inspections vitally important in averting such dangers.
Thermal imaging inspections can also detect overheated motors before they burn-out.
