Analytical formulas of the electric field near a reinforced concrete pole of a MV line
A medium voltage three-phase power line supported by reinforced concrete poles and with a pole-top-pin construction has been analyzed. An analytical model has been developed for the evaluation of the electric field, with a range of validity extending from the ground up to one quarter of the height of the poles supporting the line. The model consists in assuming that the charges on the overhead conductors are not affected by the presence of the poles, and in replacing the pole with a suitable charge distribution. In this way, new simple formulas for the estimation of the electric field that include the effect of the line supporting poles have been obtained and the analytical results have been experimentally validated.
