IMPACT OF ENVIRONMENTAL CONDITIONS ON THE CAPACITY OF POWER LINES

Abstract

This article deals with determining the value of maximum permissible current with consideration of ambient conditions. Each ambient conditions and their influence on the value of current ampacity for ACSR conductor 350/59 in comparison with ampacity given by calculation accordance the standard EN 50341 are described in this article. Static ambient conditions are given in this standard and change in the ambient conditions was neglected in calculation of the resulting value. The aim of this article is to refer the influence of the change of ambient environment and ambient conditions to the maximum permissible current.
