Abstract
This paper presents a proposed system for the continuous monitoring of conductor sag values in overhead electricity transmission lines through slope angle measurement, by using a mathematical model based on the catenary equation. By measuring the axial angle of the conductor and the slope angle by means of the double axis tilt sensor, the sag value can be calculated in case of cable swings. Using ModBus protocol the value of the tilt sensor can be read by the software application and the calculed sag value is send to SCADA. The results obtained according to the proposed algorithm developed in LabVIEW software environment showed that the system could meet the technical requirements for measuring conductor sag in electricity transmission lines.
