IEEE Std. 738-2006 method of calculation

Air temperature is 13.70 (deg C)Wind speed is 0.61 (m/s)Angle between wind and conductor is 90 (deg)Conductor elevation above sea level is 0 (m)Conductor bearing is 90 (deg) (user specified bearing, may not be value producing maximum solar heating)Sun time is 11 hours (solar altitude is 56 deg. and solar azimuth is 153 deg.)Conductor latitude is 30.0 (deg)Atmosphere is CLEARDay of year is 266 (corresponds to septiembre 23 in year 2015) (user specified day, may not be day producing maximum solar heating)

Conductor description: ALLIANCE AAAC 246.9 kcmil 7/0 Strands - Adapted from 1970's Oublicly Available DataConductor diameter is 1.430 (cm)Conductor resistance is 0.2728 (Ohm/km) at 25.0 (deg C) and 0.3192 (Ohm/km) at 75.0 (deg C)Emissivity is 0.5 and solar absorptivity is 0.5

Solar heat input is 6.827 (Watt/m) (corresponds to Global Solar Radiation of 954.792 (Watt/m^2) - which was calculated)Radiation cooling is 1.323 (Watt/m)Convective cooling is 10.178 (Watt/m)

Given a constant ac current of 131.0 amperes,The conductor temperature is 24.1 (deg C)
