An approach for condition monitoring in overhead powerlines

Abstract

It is essential to monitor the condition of Aluminum Conductor Steel Reinforced (ACSR) overhead power cables for efficient power transmission applications. Inspect the thermal ratings of power cable as a function of environmental effects, which are the affecting factors for the condition of the cable. Simulated environmental effects were introduced in the ACSR cable and the current induced temperature is observed. This paper introduces an approach for a condition monitoring of overhead power lines. The thermal model of overhead line and its function is simulated by resolving the thermal balance equations with MATLAB Simulink. In the simulated behaviour of the conductor and its surface characteristics, temperature and emissivity affects the conditions of the Powerline. The results are given that condition monitoring is a promising technique for ACSR cables to ensure the safety and quality operation.
