Single Line Electricity (SLE) 6 kV in Tal Shahar Israel is
working with virtual groundings
Experimental 6kV Single Line Electricity (SLE), was tested successfully at Start Up
Yeger Investments & Holdings Ltd Site, in Tal Shahar, Israel

Part 1. In laboratories
In the beginning I made a simulation (see results below). Our opponents had many
objections… from: "It is not possible" up to: "You use in simulations ideal elements, in real
system it will not work”, there is grounding for zeroing, so there is another line.
2
The main difference with real
system is losses in wires if it is
long line. As usual these losses
equals 3 - 10 % from
transmitting power. And we
decided include resistances as
a losses source. But revealed
that our increased and
decreased transformers have
losses and even more then
10%. Therefore we are not
using resistances and have
power loses approximately 25
%. This is more than in real
situations, but allows us
remove one of objections.

28.07.2015 we made measurements in Tal Shahar
laboratory.

The system is working and we measured all currents in it.
Part 2. In an open space
The assembly line at the site, we
started with the installation the
transmission compartment near the
laboratory
Close to the Transmission Compartment
we inserted by hammer a copper rod of
18mm of diam. and 150cm of length, for
grounding. The rod was connected to the
grounding terminal of the Transmission
Compartment

About 20m of the line is an underground line. This segment is inserted into a 1.5" plastic pipe
5
to enable later electromagnetic fields measurements
One of the big advantages of the SLE system is the
possibility to use underground and underwater
lines in a small cross section pipes with no need of
tunnels
6
Now we can make our
overhead part of line.
7
First step is to spread the 6m metallic pipes all the length of the overhead line
8
After that we install them vertically evenly along the length of the line
9
The poles (metallic pipes) are strengthened with ropes to the cactus plants to prevent failure by
10
wind blow.
The Single Wire cable is placed by a stick
with a hook on the insulated hook of the
poleat a height of 5 m
11
The first high voltage SLE moves to the Receiving Compartment
12
The remote Receiving Compartment is on its way to be
13
placed at the end of the Single Wire cable
And the receiving part has a standard
potential zeroing of general point of
inverter

12 hours 23 minutes. The first line of 6 kV is ready. One can switch on.

Below you can see measurement results, which correspond to the results of
measurements in the laboratory that are listed above. Power losses in this scheme are
losses, which give two transformers connected by usual two wire method.

No, I'm sorry:

Part 3. Virtual grounding
August 20, 2015 We are saying many times ground can't transmit energy. First its resistance
between two points is very large. Second we are transmitting current which correspond to Ohm
law, therefore cannot be another current. Grounding is making zeroing, but between two zeros
cannot be transmitting energy. And yet we keep hearing assertions “Earth in your system, this is
the second line”.
And today we
decided to show that
not transmitting
energy between two
grounded points.
We dug a ditch depth
of one meter and a
length of 5 meters.
Bed plastic lining and
poured on top of the
ground, so that the
diameter of the earth
to get 2 meters of
the pipe.
18
At the center of the earth, we have inserted a normal for grounding rod
19
Then we disabled the grounding in a transmitting part and connect this “Virtual
grounding”. All current system were the same to within 1 mA.
There is a continuous line on the ground between the transmitting and receiving
parts. Grounding (or zeroing) is local device. No connection to the earth.
Part 4. Three phases
With a single line can be connected by a system of which both or one of them threephase. To demonstrate this capability we did output SLE converter that produces an
output three phase signal.
SLE processor
Three phases / Single line
SLE processor is in patenting
process now, sorry.
21
The proposed system can replace any part of the three-phase system. The greatest economic
effect can be single-wire system instead of a high-voltage extended line. This method not only
reduces the number of wires, but also weakens the problems associated with unbalance of the
line and the reactive power.
With an oscilloscope, we were convinced that we can achieve the desired phase difference
(1200 between all two phases).
22
Conclusion
SLE system with 6kV voltage and on 50 Hz frequency is working and
not give any additional losses.
This system can work without real grounding but with virtual
grounding. Therefore ground is not second line.
The load and source of single line system can be three phase system.
