High altitude derating

WebAir at high altitude is less dense than air at sea level, reducing its convective capability and overall heat transfer capacity. Therefore, all electronics that rely on natural or forced convection to dissipate heat will experience increased air and component temperature rise for the same amount of power at higher altitudes. Thermal derating Webaltitude exceeds 1000 m” [7]. 3.5. IEC 60137 (2008-07) In this standard [8], it is said that “bushings corresponding to this standard are declared suitable for operation at any altitude not exceeding 1000 m”. The altitude correction recommended is applicable to 4000 meters with formula (5). Constant values for m are
