Safe maintenance of electrical systems using thermal imaging

Faulty electrical connections or overloaded switching systems in electrical distribution boxes, or electric drives can lead to costly production downtimes and even fire damage. Regular inspection of electrical installations and systems with a thermal camera significantly reduces the risk of such issues occurring. Using thermal imaging any abnormalities can be identified at a glance, meaning preventative measures can be taken immediately.


Electrical systems need to be operated with the greatest security possible


The challenge.

Roughly 70% of all weak spots in electrical systems can be traced to faulty clamp connections. This can be due to aging, incorrect installation, mechanical load or damage to the system components. Electrical energy then develops into heat, in some instances causing systems to overheat. This can have catastrophic consequences: Machines can break down, production lines come to a standstill, or system components have even been known to burst into flames.

Ignoring even one overheating cable can have devastating repercussions


The solution.

Testo thermal imager models can be used on all electrical systems to localise faulty electrical connections, for discovering asymmetrical load distribution or for identifying overloaded conditions of any kind. They show the surface temperature distribution of electrical components at a glance. This allows weak spots to be identified early so faulty parts can be repaired or replaced before a breakdown can occur.



Thermal analysis is completely contactless, so normal activity doesn’t need to be disrupted


The great advantage of thermographic testing with a thermal camera is that technical systems can be examined without any contact whatsoever. The continuous operation of the system can be examined without disrupting any electrical systems which are currently in use. By regularly checking a system with a thermal camera, both downtime and the risk of fire will significantly decrease. The highest possible level of security is therefore guaranteed for both the people working with the system and the system itself.

On the whole using thermal imaging lowers the maintenance and energy costs of any electrical system – by avoiding unexpected repair work and by optimising the quantities of energy used. Whether you wish to test transformers, electrical distribution boxes, switching systems or electric drives, a testo thermal camera is the perfect solution.
