Description

Interior of electrical equipment is often inaccessible for carrying out inspections. With H.VIR windows, it will now be possible to perform maintenance by infrared thermography in representative load condition. H.VIR is the only infrared window on the market to be equipped with a Wide-Band crystal (bands I, II & III), which covers the field of use of all cameras on the market (0,3 µm to 13 µm). Thermograph technicians and operators will have real protection against electric arcs. In addition, properties of our windows are no longer to be proven, by the approval of the largest electrical equipment manufacturers in the world, as well as by the large number of tests and certifications assigned to it. The H.VIR infrared optical window is available in 3 sizes: H.VIR 75 type 20; H.VIR 85 type 21 ; H.VIR 105 type 22 Characteristics : * - Use from 0.3 µm to 13 µm * - UV sensitivity : none * - Optical component quality : Parallelisme : < 3 µm Flatness : 5(2) *Surface condition : P4 (S/D : 20/40) * - Use in temperatures -40°c +70°c * - Electric insulation of the frame : Resistivity : - 4 x 1015 ohms cm2/m (20 °C) - 8 x 1015 ohms cm2/m (100 °C) Internal Arc fault Behaviour : High Voltage Tests • EFFACEC (2014) : 31.5 kA/1s (17.5 kV) • KEMA (1998) : 135 kA/0.12s (11.5 kV) • ABB (1998) : 20 kA/1s (6.5 kV) • AREVA (2008) : 16 kA/1s
