Induced voltages on fence wires and pipe lines by AC power transmission lines

A method is developed for calculating the induced voltages on fence wires and pipelines underneath AC power transmission lines. The method is based on the charge simulation techniques and takes into account disturbances of the electric field and potential due to the presence of the fence wire or pipeline underneath the line. The calculated and previously measured induced voltages on fence wires are compared. Induced voltages on pipelines underneath 230 and 380 kV lines were measured. The results are correlated with the calculated values and discussed in the light of electric field induction on objects adjacent to AC power transmission lines.<
