Structural elements of high-voltage overhead power lines located underground are subject to chemical corrosion. In addition, they are affected by stray currents flowing in the ground caused by current-carrying elements of the overhead power lines (OPL). In the present study, a mathematical model has been developed to qualitatively and quantitatively evaluate leakage currents and spreading currents along the structural elements of OPL supports. The results are presented here.

Abstract


Structural elements of high-voltage overhead power lines located underground are subject to chemical corrosion. In addition, they are affected by stray currents flowing in the ground caused by current-carrying elements of the overhead power lines (OPL). In the present study, a mathematical model has been developed to qualitatively and quantitatively evaluate leakage currents and spreading currents along the structural elements of OPL supports. The results are presented here.
