We have proposed the voltage-current sensor embedded in a ceramic insulator for the real-time observation of the power factor in three-phase power distribution systems and carried out the finite element analysis to investigate its characteristics and verify its feasibility. However, the ceramic sensor has problems in cost and a burning process in manufacturing to result in the deformation from the designed form. In the paper, we propose a resin molded type of voltage-current sensor with dual search coils for the current sensor part based on the finite element analysis and discuss its steady state electromagnetic behaviors theoretically and experimentally.
