We have proposed the voltage-current sensor of resin molded type for measurement of the power factor and harmonics. To grasp the characteristics of the conventional prototype sensor and the problem in its practical use, we have conducted the finite element analysis for that. There occurred problems on the cost and the practical usage in making use of the sensor consequently. Therefore we have redesigned the prototype sensor, where the current sensor designed based on the FEM and a ready-made voltage sensor have been incorporated. In this paper, we will describe the feasibility field experiment of the present sensor in the practical 6.6kV distribution system and show that the sensor can measure the power factor and harmonics for the horizontal and vertical power line systems successfully.
