WHITEPAPER: THERMAL SAFETY FOR EMC TEST FACILITIES

High-power immunity testing and the increasing number of E-vehicles introduce significant heat sources, such as absorbers and batteries, which can lead to overheating and fires. Monitoring and preventing fires, as well as surveilling components of the DUT, are essential in EMC test facilities. Infrared thermal cameras are the most efficient way to monitor temperature, but not all cameras are suitable for EMC environments due to their limited temperature range and potential interference. Shielded cameras like the PONTIS EMC IRThermo6 are recommended for their ability to handle higher temperatures and avoid measurement interference.

Considerations to be made selecting a thermal camera (amongst others):

• Viewing Area: Lenses must be made of special materials like Germanium, and motorized focus can be helpful for remote adjustments.
• Temperature Range: Cameras should be able to handle temperatures up to 150 °C, suitable for EMC test facilities.
• Positioning: Mount the thermal camera alongside a regular video camera to accurately see and position the monitored area.
