Analysis of Electric Field in Seawater Influenced by Conductivity and Shape of the Object

Electric field measurements in seawater will affect the target electric field. In order to improve the accuracy of the electric field measurement, the influence factors of the object on the distribution of the electric field in seawater are studied by the finite element method, and the distribution of the distortion electric field is determined. The simulation results show that the magnitude of the distortion peak value and the distortion area are affected by the conductivity and the shape of the object. When the conductivity of the object is smaller or larger than the conductivity of seawater, the effect on the electric field distribution is opposite. The larger the curvature of the object is, the larger the peak value of the distortion is, but the smaller the distortion area is.
