We are talking about preventive maintenance here since the thermographer can safely detect a hot spot and report it so that corrective action can be taken before an accident occurs. However, it should be remembered that preventive maintenance by thermography must be planned and cannot be carried out without human intervention. Its effectiveness in terms of anticipation therefore depends on the regularity with which it is conducted.
Is it possible to automate the inspection of electrical installations? Yes, with modern technology it is now possible to monitor equipment permanently and send reports automatically when thresholds are reached. This is predictive maintenance.
Connected predictive maintenance for continuous monitoring
Predictive maintenance relies on the combined use of thermography, artificial intelligence and the Internet of Things. It aims to optimize the anticipation of risks by defining thresholds. Automated and continuously operating, predictive maintenance requires no planning or intervention by a thermographer.
Wintech Groupe has designed and developed the autonomous UTC SD Smart Camera, a connected optoelectronic device integrating a microbolometric sensor similar to an infrared camera. This device is placed directly in an area to be monitored or installed on the enclosure of electrical equipment like an IR window.

In case of detection of hot spots, an audible alarm can be triggered on site and email or SMS alarms can be sent. A preliminary configuration is required to define the temperature threshold for triggering alerts. Below the alert threshold, the UTC SD Smart Camera also makes it possible to simply monitor equipment from a distance. The data collected can be used to better understand the “behavior” of equipment over time (stronger resistance or, conversely, a recurring defect) and plan interventions.
The term “predictive” refers to the fact that monitoring is continuous, on charged equipment, with an alert triggered at a desired temperature (below the critical threshold in order to facilitate corrective action as early as possible). Permanent monitoring with the temperature threshold significantly improves the anticipation of risks related to electrical installations by allowing intervention before any incident.
