Thermal imagers facilitate evaluation of the heat status of low, medium and high-voltage systems. You can use them to identify electrical components or connections with thermal anomalies and to implement the necessary measures. This prevents dangerous fire risks and costly production downtimes.
Thermography in the inspection of switch cabinets - top-level maintenance H3>
In electrical installations or cables, increased temperatures are always an indication of an overload, an imminent malfunction or an existing defect. The technology of thermography is particularly useful in the maintenance of switch cabinets, as the measurements can be carried out non-contact and at a safe distance. Anomalies can therefore be detected and counter measures can be implemented.
Detection and storage of measuring site - automatically
The SiteRecognition technology also supports efficient and reliable inspection routing for lots of similar switch cabinets. The thermal imager automatically detects the measuring location and stores the measured thermal images in defined folders. Therefore the thermal images of the switch cabinets can be analysed conveniently and safely on the PC.
Ideal thermal imagers H3>
Not only can you use the high-resolution testo 885 in camcorder format (with rotary handle and foldable and pivotable display) to reliably detect damage to mechanical system components as part of your mechanical maintenance. The patent-pending SiteRecognition technology also provides extremely efficient inspection route management.
Maintenance of electrical installations: conductors and connections H3>
Maintenance of electrical installations: electrical components H3>
In case of electrical components, heat distribution within the individual components is also significant, as well as the connections and access lines. Different temperatures within maintenance indicate the operating status, but can also be indicative of a malfunction. The image shows an overloaded electrical fuse. It may be that this fuse is too small, or the electrical components are producing excessive current.
Maintenance of electrical installations: transformers H3>
Depending on the type of insulation, the connections, cores or insulation in components of medium-voltage installations such as transformers can be inspected for thermal irregularities.
Maintenance of electrical installations: overhead power lines H3>
The electrical connection points and insulators for overhead power lines in substations or the overhead power lines of high-voltage systems can be checked for maintenance purposes. Typically, these locations are difficult to access. Lots of locations can be inspected thermographically using a telephoto lens with correspondingly high resolution, conveniently from the ground.
Maintenance of electrical installations: control and regulation systems H3>
EMCR systems (electrical, measurement, control and regulation technology) are operated at low voltage and can be inspected quickly and easily using thermography. These systems are normally maintained using thermal imagers with a high detector resolution. The higher detector resolution makes smaller details visible. Thus, even the smallest electrical components can be analysed thermographically.
