Abstract :
The real-time observation of a power factor will be indispensable for the maintenance and the stable voltage regulation in three-phase power distribution systems. To carry out the observation, the authors have devised and proposed an insulator built-in type of voltage-current sensor. According to their previous investigations on the sensor, it was found theoretically that a serious phase shift in the measured waveforms of the voltage and the current might occur owing to the electromagnetic interference of each phase. In the paper, they propose the compensation winding for the current sensor in the horizontal and vertical power distribution systems
