12. APPENDIX
The standard condition of rated power output:
Altitude: 0m
Ambient temperature: 77°F (25°C)
Relative humidity: 30%
NOTE:
Relative humidity 60% correction factor C-0.01
Relative humidity 80% correction factor C -0.02
Relative humidity 90% correction factor C-0.03
Relative humidity 100% correction factor C-0.04
Example:
Rated power ( PN ) 2.8kVA generator (Altitude: 1000m) Ambient temperature: 35°C,
Relative humidity: 80%
P=Pn*(C-0.02)=2.8*(0.82-0.02)=2.24kVA
