The calculations of load losses of electricity in the wires of overhead power transmission lines in the vast majority of cases are carried out by «traditional» methods, in other words without taking into account the change in the resistance of the wires. Such calculations have significant infelicities, and the existing methods of accounting for factors affecting the temperature of the wire are complex, volumetric in calculations, and require comprehensive information about the weather, and therefore are not used in practice. Recommendations for improving the accuracy of afore-referenced calculations through the application of the method of corrective coefficients were developed in this article. The focus is on the practical application of the recommendations.
