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 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. Web10 de dez. de 2024 · Posts: 5. Adjusting water heater for high altitude. I am a new owner of an A-frame. The water heater manual says it works great up to 4500' elevation, then must be "derated" 4% for every 1000' elevation.
