Infrared thermography

Thermography: electrical diagnosis par excellence

The constant evolution of safety standards requires the constant updating of equipment. However, this remains a difficult task that can result in high capital costs, especially when it comes to checking an electrical circuit.

Infrared thermography is an electrical and mechanical intervention that makes it possible to raise the operating temperature of all the elements on site, and to produce a report with a photograph of the readings to prepare corrective actions in order to pre-empt breakdowns. It allows buildings to be analysed quickly and thoroughly, identifying and labelling construction and network defects.

Thermography is a method for maintaining electrical installations that prevents fire risks, guarantees human safety, and optimises the production system. We inspect electrical installations using infrared thermography under the conditions laid out in the Q19 certificate (issued by the CNPP according to standard no. APSAD D19).

On-site surveys of:

  • Operating temperature of electrical connectors
  • Temperature of any electrical device in operation
  • Preparation of a hard-copy report with photographs of the readings
  • Report analysis and conclusions for corrective actions

We provide services for:

  • Cabinets and LV switchboards
  • HT cell and technical room  
  • Transformer

Need / Context

CEE R SCHISLER is one of the leading European manufacturers of paper bags and cardboard cups. It supplies fast food chains and the biggest retailers, meaning that it must avoid all production stoppages. Its ageing equipment is a primary concern.


To respond to this maintenance issue, we offer vibration analysis of our customer’s workshops consisting of extruders, reels, printers, cutters, etc. We inspect the 90 main motors (from 15 to 250 KW), flagging up those products in need of maintenance operations. Convinced by the results of our first campaign, CEE R. SCHISLER went on to offer us a 3-year contract.
