The precise estimation of the electric power at the consumer end-side has been eagerly demanded for the maintenance, control and the stable voltage regulation by electric power companies. There are several approaches to the observation of the power factor based on the practical waveform of both the voltage and the current. However, conventionally each sensor has been installed on power distribution lines independently. The measurement systems will be large and complicated to result in no maintenance-free systems.To carry out the wave form observation for power factor, we have devised and proposed an insulator built-in type of voltage-current sensor with the two current sensor coils, that are connected with opposite polarity to each other. According to our previous investigations on the sensor, it was found out theoretically that a serious phase shift due to the electromagnetic interference of each phase in the conventional sensor will be successfully compensated.Although the above insulator built-in type of voltage-current sensor has good performance characteristics for concurrent measurement of both voltage and current waveforms, the burning process will be required for the formation of an insulator. To overcome such a practical production problem, we have designed and implemented the new resin molded type of voltage and current sensor using the polyacetal resin material.Finally, based on the theoretical design, the prototype of the voltage-current sensor with above two coils has been fabricated and it has been found out experimentally that the effect of compensation on the phase shift in the current sensor could be obtainable in the simulated three-phase power distribution system in our laboratory.

电力公司对用户端的电能质量进行准确的估计，以便于维护、控制和稳定的电压调节。有几种方法可以根据电压和电流的实际波形来观察功率因数。然而，传统上，每个传感器被独立地安装在配电线路上。为了实现功率因数波形的观测，我们设计并提出了一种绝缘子内置式电压-电流传感器，该传感器具有两个电流传感器线圈，它们以相反的极性相互连接。根据我们以前对该传感器的研究，理论上发现，由于传统传感器中每相的电磁干扰而引起的严重相移将被成功地补偿。虽然上述绝缘体内置型电压-电流传感器对于同时测量电压和电流波形具有良好的性能特性，形成绝缘体需要燃烧工艺。为了克服这样的实际生产问题，我们设计并实现了使用聚缩醛树脂材料的新型树脂模制型电压和电流传感器。最后，在理论设计的基础上，电压的原型制作了具有上述两个线圈的电流传感器，并在实验中发现，在模拟中可以获得对电流传感器中的相移的补偿效果。三相配电系统在我们的实验室。
