Determination of phase sequence and voltage level of double-circuit overhead conductors is investigated using non-contact sensors situated on a moving platform at ground level. Based on the investigation of the electric field beneath double-circuit transmission lines through Finite Element Analysis (FEA) simulations and laboratory experiments with a scale model, a determination methodology is proposed. Experiments taken beneath 400 kV double-circuit transmission lines are presented in detail. Analysis of the experimental results shows that the proposed determination methodology can successfully evaluate the phase sequence arrangement and voltage level of high-voltage double circuit conductors.
