WebDensity Change at High Altitude. At sea level, the density of air is .075 lbs/ft 3 (1.19 kg/m 3), see Table 1. This value is created by all of the other molecules in the atmosphere weighing down on the molecules at sea level. As the elevation increases, there are fewer molecules weighing down and the density of the air decreases. WebAt higher altitudes, less-dense air has a reduced capacity to insulate against flashover. Most electronics are designed to operate at altitudes up to 1000-2000 metres. Above this, it may be necessary to purchase electronics such as speed controls designed specifically for use at high altitudes.

Web30 de mar. de 2009 · At high altitudes the air is thinner, less dense. This thin air has less heat-carrying capacity. At sea level, 1,200 cubic feet per minute (cfm) of air can carry 36,000 Btuh. However, at 5,000 feet, the thinner air carries less heat; about 1,430 cfm are needed to carry 36,000 Btuh, as will be displayed in the example below. Web8 de jul. de 2002 · Heat dissipation would be a concern at high altitudes. But the largest reason equipment is derated is because the dielectric strength of air decreases as the altitude increases. As the dielectric strength decreases then a potential of 500 volts at sea level may perform fine but at 10000 feet it may flashover. chronomics priority post box

WebAltitude can have an effect--but probably from two mechanisms... One is temperature--Above ~5,000-7,000 feet, many electrical devices need power derating because there is less dense air and less cooling effect. The other is that many batteries have a pressure vent and less air pressure will let the batteries vent at low pressures.
