High altitude derating factors for electrical systems

When operating in an environment with lower air pressure like high altitude or airplane cabins, the cooling capacity has to be derated compared to that of sea level. A rule-of-thumb formula to note: 1 - (h/17500) = derating factor. Where h is the height over sea level in meters. And the result is the factor that should be multiplied with the cooling capacity in [W] to get the cooling capacity at the specified height over sea level.

Because air is less … 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 WebBelow, Table A illustrates the recommended derating by altitude for Joslyn Clark's 7.2kV, 3.6kV, and 1.5kV Vacuum Contactors. Note: All vacuum contactors are fully qualified at 2000 meters, and current derating starts when altitude exceeds approximately 2000 meters.
