Outline of Final Research Achievements

In this study, the author has payed attention to the pole switch, that is installed in power distribution systems, is connected to the Internet and remote-controlled, to introduce the resin molded voltage-current sensor, that observes and measures both the power status and the harmonics, into the pole switch. In practice, he has designed and implemented the simulated pole switch box made of iron and installed the above power status sensors, that have been molded in the polyacetal resin, in the simulated three power lines inside the iron housing.

The current sensor, that comprises a pair of two coils connected with reverse polarity for each other, has been examined under 300 A phase current condition to display the wave form of line current with harmonics successfully regardless of the inside of an iron box. Also, the voltage sensor with a pair of electrodes, has been examined under 3,600 V of line to line voltage to show the voltage wave form well.
