Here's the Babelfish translation of one of the above pages, just the section relating to LV utilization:
* Three phase circuit 4 line type 415/240V neutral grounding system: The nineties compared to, subterraneanizing and the like the electric line and also it started being used the urban district whose load density is high for the center.
* Three phase circuit 3 line system 200V (three phase circuit power exclusive use): It is utilized for the user which utilizes three phase circuit 200V load of the small-scale store and the like as the retreat seeing line.
* Electric light power common three phase circuit 4 line system 200V/100V (use electric light power common transformer or strange capacity V wiring)
* Single-phase 3 line system 200/100V: It is used for the small-scale user which utilizes lamp load. Main current for general home after the eighties.
* Single-phase 2 line system 100V: It is used for only the pulling included line of extremely small capacity. At one time this system was main current in one for home.
