Iriss has announced that its VPFR infrared window has passed 63kA, 15kV, 30-cycle arc resistance tests conducted to the required IEEE C37.20.7 (equivalent to IEC 62271-200) standards.

The tests were carried out on Eaton VC-W Metalclad switchgear at the KEMA Powertest Lab in Pennsylvania.

Arc flash incidents, which are potentially catastrophic electrical short circuits, can produce temperatures in excess of 35,000F, causing explosions or ‘arc blasts’ that create molten shrapnel carried by pressure waves measured in thousands of pounds of force.

In addition to the damage to plant assets and lost production time, more than 2,000 workers are said to require treatment at burn centres each year as a result of serious arc flash incidents occurring daily across North America alone.

Standards organisations such as IEC and IEEE have prescribed test procedures to certify certain types of electrical distribution equipment, such as metal-clad switchgear, for resistance to the effects of arcing due to an internal fault.

The Iriss VPFR infrared windows, recently used as accessories in a 63kA, 15kV, 30-cycle arc resistance test and the windows, as part of the switchgear system, were shown to contain the effects of the blast.

IRISS

IRISS is the manufacturer of the world’s first and only industrial-grade infrared windows. Their design is based on the 17 years of field experience that the company’s founder, Martin Robinson, gained as a Level III thermographer. And it is this end-user perspective that makes IRISS unique in the industry.

IRISS designs and manufacturers IR (Infrared) windows and safety solutions for electrical assets and provides training for electrical engineers.

IRISS provides its customers with unsurpassed quality at every touch point and focusses on continuously improving infrared (IR) window technology, building reliable products, exceeding customer expectations, whilst remaining a science-based R&D company and protecting their polymer IR windows through the IRISS Unconditional Lifetime Warranty.

IRISS industrial-grade IR windows facilitate safer, more efficient inspections of energized electrical equipment when compared to traditional crystal windows. IRISS award-winning, IR window designs feature a durable transparent polymer lens that allows visual, UV, and short/mid/longwave IR spectrum inspections. And…is available in custom shapes, sizes, and colours to fit the needs of any application.

As solution providers, the team at IRISS brings a multitude of experience from world-class maintenance programs together to meet the individual needs of commercial, industrial, marine, power generation and government maintenance programs.
