Security logic behind the infrared (IR) window
By installing a certified correct infrared (IR) window to inspect switchgear and motors, companies are more likely to meet US NFPA70E standards: Work Area Electrical Safety Standards. The infrared window allows technicians to inspect electrical equipment without removing the panel cover (this can greatly reduce the occurrence of arc explosions).
The infrared window provides a solid barrier between the thermographer and the live conductor. The design of the infrared window not only reduces the arc triggering effect, but also provides a safer working environment. More security applications include:
Security plan changed from passive to active
● In the past, many facilities waited until an arc flashover accident occurred to install infrared windows, but such accidents occurred more and more frequently, and many companies are retrofitting existing panels in advance.
• Use an infrared window that supports thermal infrared and visible light inspection to actively protect the thermal imager in the event of an arc flashover.
Check live parts with the panel closed
● Through the infrared window, it is easier to check frequently under closed or protective conditions, effectively reducing the risk of serious injury or death.
● Scanning through the infrared window is considered a non-invasive task that can effectively reduce the risk of electrical hazards.
Increase inspection speed
●After installing the infrared window, the inspection time can be saved because the screws are not needed and the cabinet door is removed.
● Work permit requirements and NFPA 70E procedures are greatly reduced.
• Installers do not have to wear fully armed personal protective equipment (PPE).
• Faster inspection times allow for more frequent inspections.
Ensure that only trained and authorized personnel can remove the infrared window to complete the inspection or scan
• Many infrared windows provide a version of the security lock when the infrared window is in a non-secure area. This prevents unauthorized personnel from operating the infrared window.
Whether the staff is taking thermal images or inspecting equipment, the infrared window enhances the safety of personnel in potentially hazardous conditions. Durability is critical in terms of infrared windows. Be sure to use an infrared window that can withstand arc explosions and fully realize that durability will change over time.
