 In the laying of high voltage power lines, special cases exist where there is a large gap between the supports, which must be controlled by surveying methods during the installation process. The control involves the calculation of the angle corresponding to the arrow on the conductor at a given temperature. As there may be signifi cant variations in temperature between the ground and the conductor (in its fi nal location), it is necessary controlling this variation. It has been developed a system for measuring the temperature of the conductor ends at the time of installation. This information is transmitted to a computer through an application developed in Matlab. This one automatically calculates the average temperature of the conductor, and, at the same time, it calculates the angle that should be the lowest point of the conductor in time to be fi xed. On the other hand, the developed application also allows verifying by surveying methods whether the sag of a fi xed conductor complies with current regulations: it is possible doing it in situ, without having to be under the power line.
