Abstract :
The authors 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 of it to investigate its characteristics and verify its feasibility. However, the sensor will have problems with production costs and manufacturing process. In the paper, the authors propose a new resin molded type of voltage-current sensor with a compensation winding for the current sensor part and discuss its electromagnetic behavior and the constitution of four kinds of electrodes theoretically
