Three-Phase system disadvantages

June 24, 2016   

The three-Phase system has the following disadvantages:

  • Many expensive wires ( three or four);

  • Large expensive supports for wires;

  • There are intermediate stations sometimes every 30 km;

  • Underground and underwater three phase system are very expensive

  • Strong negative environmental impact;

  • Large number of wire breaks

  • Large energy losses

  • When connecting the load on the different phases, there is a distortion of the phase voltages. In addition to the harm caused by the poor quality electrical power directly to electric receivers, there equalizing currents causing extra power consumption.

Single Line Electricity (SLE) system allows transmit three phase signal by one wire and without these disadvantages – Patent US 9246405.

Дано описание предложенной автором однопроводной системы передачи электроэнергии. Система может работать на любой частоте, включая постоянный ток. Она может быть применена для передачи трехфазного сигнала и для сбора энергии от “зеленых” источников. Подробно описаны проблемы, связанные с обнулением (заземлением) сигнал и передачей энергии , используя подземные и подводные линии. Приведены данные о двух опытных системах.

Three Phase System vs One wire Electricity

November 28, 2015   

Patent  US 9246405


The three-phase system has been widely accepted mainly because it enables building efficient generators and motors. However, there are many drawbacks of the three-phase system, which are described in numerous publications.

The main drawback of three-phase system is need of expensive and excess lines, which connect source and load. If three wires are used, rather than two or one, there is mutual influence of the currents in the wires. The wires must be apart on distance in the air, in underground and in underwater. It increases a cost of the electrical system.

The SLE system was proposed and checked. Two SLE systems (on 220 V and on 6 kV) are operating now in Israel.

SLE can operate at all frequencies, including 50 Hz, 60 Hz and DC, at all voltages and at any power of electrical energy.  In this case, grounding is not a channel for the transmission of energy or information.

SLE can include:

  1. Automatic Phase Tuning (APT)
  2. Compensators of Cable Capacitance per unit length (CCC)

SLE (B-Line) method allows:

  • Combining three phase generator and three phase motor with one wire only;
  • Significantly reducing the number of wires on the globe;
  • Significantly reducing the cost of construction of high-voltage electrical systems;
  • Using features of underground and underwater power lines SLE for energy transmission without intermediate stations;
  • producing electricity at the place of gas or other energy sourceand transferring it to the place of consumption using single wire under the ground, which in many cases is more profitable than transferring gas ;
  • Reducing number of accidents associated with electrical systems;
  • Reducing losses in transmitting by one wire instead of three phase common wires;

Single Line electricity without ground connection

September 20, 2015   

Dear colleagues and friends

You can see now continuation of our previous films about Single Line System (SLE):



Unfortunately this is amateur film.

But it gives answer on one of two most popular objections on single line method. This objection is about ground connection. This film shows that ground cannot transmit electrical signal in real systems.

On second objection: “This is can be never”  I don’t know answer yet
