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. WebAltitude In areas of high altitude, air pressure drops reducing the air density. This can create problems with generator start up if not accounted for since air is crucial for ignition in any type of generator. Another factor that gets affected is availability of ambient air to facilitate heat dissipation from the generator.
