Currently in the Netherlands, TenneT TSO plans to build more than 100 kilometer of new overhead line. For these overhead lines it is planned to use the 400 kV Wintrack bi-pole configuration. It is envisaged to use concrete poles next to steel poles as a cost effective alternative. To date there is less to no experience using concrete in 400 kV overhead lines. It is aimed to investigate the appropriateness of concrete poles for 400 kV applications. A number of electrical tests have been performed to examine the feasibility of steel reinforced concrete. This paper will address the behavior of the concrete, including steel reinforcements and pre-tension steel, with respect to the presence of a continuous electrical field, short circuit currents and continuous high currents in the steel. To investigate the influence of the electrical field on the steel reinforcement, probes were installed to monitor degradation of the passivation layer around the steel rods. The quality of the passivation layer is not affected in a negative sense. The tests show that a continuous high electrical field does not lead to any damage, discoloration and coarsening of the concrete surface.
