Thermography for reliable power distribution and power generation
It is in the best interest of power stations and utility companies to ensure that no interruptions occur, from the energy generation process through to distribution. Testo thermal imagers maintain the integrity of electrical and mechanical components as part of this preventive maintenance.
Non-destructive thermographic testing can reduce costly system malfunctions or downtimes.
It is absolutely essential to prevent energy distribution systems from malfunctioning due to the far-reaching consequences. Faulty connections on high-voltage masts can be particularly critical here.
With thermal imagers, you can check out temperature increases non-contact and from a safe distance: without putting yourself at risk and without having to switch off the high-voltage system.
Power distribution systems
Thermographic inspection – to ensure smooth operation
Assess heating on disconnectors and circuit breakers from a safe distance
Non-contact inspection of transformers, insulators and screw connections
Precisely identify material fatigue and cable ruptures
This is how it works in practice

FOV calculator for Testo thermal imagers
The FOV calculator shows you quickly and easily just how small the measurement object can be in order to be detected (IFOV geo) and reliably measured (IFOV meas) at the selected distance. Try it out for yourself [here] and put together the kit consisting of imager and lens that is right for you.
Other advantages of Testo thermal imagers
testo IRSoft professional software
Use the testo IRSoft report wizard to generate professional reports quickly and easily – or use the software’s report designer to create customized templates in line with your own personal requirements. The software can be downloaded free of charge and without a licence.
testo Thermography App – be smart and networked
With the testo Thermography App you can quickly and easily share images from your smartphone or tablet with your colleagues
Keeping limit values safely in view
The hot spot function immediately displays the hottest spot in the image. In addition, points that exceed defined limits can be highlighted in colour using the alarm function.
The clever combination of touch display and the tried-and-tested Testo joystick will make your work processes smoother and more efficient.
Fold-out display and rotatable handle
The rotatable, fold-out display and the ergonomic rotatable handle allow measurements in difficult-to-access places.
6.6° x 5° super-telephoto lens:
- Small field of view for maximum resolution
- Particularly suitable for measurements on objects that are far away, e.g. power lines
- Easy to handle: no additional lens holder needed
Maintenance of mechanical components
Heat generation in mechanical components in power-generating plants may indicate an elevated level of stress. This is caused, for example, by friction, faulty alignment, component tolerances or a lack of lubricant.
The main advantage of infrared measurement: it is non-contact and can therefore be carried out during operation and from a safe distance.
Maintenance of electrical installations
Testo thermal imagers facilitate evaluation of the heat status of low, medium and high-voltage systems. Thermographic images lead to the early detection of defective components or connections, so that the necessary preventive measures can be introduced in a targeted way.
This minimises dangerous fire risks and avoids costly production downtimes for energy producers.
