Single-wire transmission line


  • Revolutionary method of electrical transmission which requires only a single wire providing over 50% savings
  • Simple reconfiguration of conventional power line equipment
  • Virtually eliminates transmission losses and corona radiation allowing for an eco-friendly alternative
  • Long distance power transmission with substations only every 1,500 km opening a world of opportunities for terrain and submarine application

Single Channel Systems

  • Radio Systems
  • Fiber Optic Systems
  • Waveguides
  • Why can’t electrical transmission be one channel?

Earlier Single wire Attempts

  • Single-wire electrical energy transmission - Nikola Tesla (1890)
  • The Goubau line, a single-wire transmission line at microwave frequencies - Geog Goubau (1950)
  • AFEP experiment - Stanislav and Konstantin Avramenko (1993)
  • All the above create transformations in the frequency and signal causing huge losses

Single Wire Eaerth Return

  • Current Single Wire System in limited use
  • Ends of the sources and loads are connected to the ground
  • Excessive losses of energy and an alteration of the signal waveform for distances greater than 10 miles
  • Simply uneconomical

How SLE Works

In this two line system (A-Line), the currents in each wire are in opposite phases

  • The source (generator) produces two signals of opposite phases
  • The current will flow through the load with opposite phases as well

Main Idea: use inverters to get the same potential polarity in both wires

B-Line: Wires with the same (equipotential) currents can be combined

Instead of using two or more channels

We can use one channel in electrical systems as well
