Power reduction factor of generators at different altitudes and temperatures
Power reduction factor of generators at different altitudes and temperatures
When the ambient temperature exceeds 40 degrees, the generator needs to reduce power.
Generators at an altitude of more than 1000 meters also need to be reduced in power.
The figure below shows the power reduction coefficient of the top grid products at different altitudes and temperatures:
