The main goal of this article is to compare traditional three phase system with one wire three-phase system. There are several obvious advantages of one wire system, for example cost, reliability and other. But there is a problem as well, connected to reactive power in both systems. This article proposes explanation of reactive power emergence in systems SWER, three-phase and in their one wire versions. 展开更多

The purpose of this article is to remind of the past and present problems of creating single wire electrical systems. This article presents a new one wire electrical transmission system named B-Line which uses one line only and does not use ground as a second line. The proposed method is to work on all frequencies and on all communication systems including DC systems. It also proposes to work on the concept of the single-pole signal source and single-pole signal load. It illustrates the possibility of cutting the cost of electrical lines and several other advantages in the fields of high frequency communication lines and antennas. 展开更多

This article is an attempt to answer student’s (and not only students’) questions about the possibility of inventions nowadays in the field of electricity. The student is confident that nowadays everything is clear. Large firms do everything which is needed. And the time for inventions is over. But in fact, many things are not so clear, and a new Tesla may appear. 展开更多
