A multiple unit nuclear generating station has adopted the C-Range Hawk IR Sightglasses to safely enable IR thermography scans of Medium Voltage (MV) motor junction boxes. MV Motors, in particular the junction boxes, are the keystone for a nuclear generating station, providing a junction between large field cabling and the rotating machinery used to power coolant pumps and other critical drives. The Electrical Safety Standard, NFPA70E, has driven the increase in safety awareness, especially in the electrical IR thermography community.
Due to arc-flash hazards, it is not practically and/or safe to remove large, heavy motor box covers to all IR Inspection.
Two IR Windows were installed into each MV Motor Junction box allowing an IR thermographer to inspect both field and motor side cable connections at the motor during running.
Arc-Resistant C-Range IR windows using the revolutionary CLIRVU optic material can protect an infrared thermography should an arc-flash occur In addition to standard electrical requirements, the nuclear industry must also consider the effects of seismic activity on the installation.
The revolutionary fixing method used by Hawk IR ensures that dielectric clearances are not reduced - a MUST when retrofitting - but has also passed the stringent requirements of the nuclear industries seismic standards.
The installation of Infrared Windows, the nuclear industry is leading the field in electrical safety and reliability.
