For electrical current to flow: Electrical thermography

Thermographic inspections of electrical systems prevent faults and damage. A thermal imaging camera renders defects in the electrical system visible!

In what condition are the power lines concealed in a wall or equipment? Is the plastic sheathing brittle already? Are the connections faulty? If a power cable or connection is about to come off or the insulation is bursting open, it doesn’t take much before there is some greater damage. To prevent cable fire and failures of the electrical system, an early detection and elimination of the cause of such deficiencies at the lines is indispensable. Thanks to detailed infrared images defects at the lines can be located and documented at an early stage. The high-quality thermal imaging cameras from Trotec look where the eye can’t see – directly at the concealed lines.

Power works with considerable force and warmth. But what it really looks like inside an electronic system and in what shape individual cables and power lines, their insulation and connectors are, can often only be guessed at. For what actually happens particularly in larger systems, in walls, control cabinets or even control rooms is hidden from sight. They have to be regularly checked for proper functioning, which is not only demanded by legal requirements but also by insurance companies. The reason: fire prevention. Such electrical systems carry the risk of fire connoting considerable damage for employees, for the company and the production.

Looking into hidden depths: rendered possible by infrared

Often control rooms are in use for years and years. Over time old cables can become porous due to the exposure to light, heat and chemical processes. When the plastic sheathing of cables dries out, becomes fissured and brittle, this could turn into a rather prickly affair. Then there is also the oxidation at contacts and fusing – also damages which appear as time goes by. Using thermal imaging cameras it is possible to look underneath the exterior of electrical equipment and to render precisely these types of damages visible. Owing to the infrared technology these special cameras detect temperature differences at the damaged areas. With a thermal imaging camera from Trotec these spots are rendered visible and can be documented in every detail. Defects at smaller control cabinets are eliminated as quickly as possible. In case of larger systems and control rooms the damage can be put down for later repair during a scheduled standstill. Trotec’s range of products includes several models for the detection of suspicious temperature differences: e.g. the thermal imaging cameras of the IC series, the thermal imaging cameras of the EC series and the thermal imaging camera tablet AC080V. All of the above reliably and accurately cope with measurement engineering tasks.

  • Indicative fever screening during an infectious disease epidemic

    In times of infectious disease epidemics, the early detection of infected persons becomes all the more important. Highly infectious viruses, such as norovirus, SARS-CoV-2 (corona) or even H5N1 (bird flu) don’t respect closed doors, international borders or access restrictions. The pathogens spread across the world during a pandemic and the most important measure to help contain them is the early...

  • Observing wild animals

    In addition to binoculars, there is mainly one piece of equipment that is indispensable for observing wild animals: a thermal imaging camera. With the help of infrared images, animals can be tracked even in poor visibility conditions and total darkness. With the thermal imaging cameras of the IC series Trotec provides reliable observation equipment. Handy, precise and resistant – and all of this...

  • Checking the health of trees

    The safety in parks, on paths and in the forest must be ensured by either the owners or the public administration responsible for the area. Their legal duty of care includes assessing the trees' health condition professionally in order to be able to take the necessary measures. If it turns out that a tree is heavily damaged, it must be removed as quickly as possible to avoid endangering...

  • Equine thermography

    The horse is one of the most popular animals in Germany. If a horse suffers a disease or an acute injury, however, costs for medical examinations can be comparatively high. The later the physical impairment is detected, the more time-consuming and cost-intensive the healing process will be. This is why thermography is increasingly used for prophylaxis, acute diagnostics and rehabilitation.

  • Infrared thermography for border security

    Monitoring protected areas and borders is a highly responsible task. For here, everything revolves around security. The border guards' task is to track down and stop unauthorized persons. Since intruders mainly rely on poor visibility conditions giving them cover, border guards must be particularly prepared for missions at night and in dense fog. This requires the use of equipment of the latest...

  • Location in waters

    At sea good visibility is extremely important, especially at night. A fact well known by every sailor who has been out on the open sea after dark before. Amateur mariners and search and rescue teams who want to navigate their fleet unerringly and then need to locate other boats and persons in the water make use of the infrared technology. For Trotec thermal imaging cameras produce detailed and...

  • Search for oil slicks

    Once an oil slick reaches the coast, the damage becomes particularly great. Entire animal populations are threatened, and the flora is destroyed. Depending on the size, it may even end in an oil pest. This is why conservationists and task forces work at full capacity in order to spot and eliminate the oil as quickly as possible. Particularly poor visibility and heavy swell require a keen eye. This...
