Note: When the relative humidity is 60%, the modified coefficient is C-0.01
When the relative humidity is 80%, the modified coefficient is C-0.02
When the relative humidity is 90%, the modified coefficient is C-0.03
When the relative humidity is 100%, the modified coefficient is C-0.04
Counting example:
When the rated power of generator is P =5KW, altitude is 1000m, ambient
temperature is 35
, relative humidity is 80%, the rated power of generator is:
P=P
(C-0.02) = 5
(0.82-0.02) = 4KW
