Very often current-carrying capacity is treated as the constant parameter, at most dependent on season of the year. Presented analysis takes into considerations the current temperature of the air, insolation, wind velocity, humidity and rain. The paper presents the results of calculation for different cases of weather and situations in power system. Above mentioned weather factors create possibility for additional transmission of power by overhead lines.
