The electric power is in dispensable and its stable supply is always expected. A stable supply needs the real?time observation of load conditions by measurement of power factor. In addition, the various faults have been caused from the harmonic voltage and current. In the authors’ laboratory, the sensor, which simultaneously measures both the wave forms of the voltage and current without contacting the conductors in the three?phase power distribution system directly, has been designed and implemented. Using the sensor, we will observe the power factor and harmonics from the measured wave forms of voltage and current in power distribution line. However, the experimental sensor was designed to be applied to the 6.6kV power distribution system in the dielectric strength. The authors will propose the sensor for the 22kV power distribution system and investigate the output characteristics of this new sensor from numerical results based on the finite element method.
