The SWET (Single Wire Energy Transmission) system is being developed by scientists from the KENER Department (RE-5). The system's concept involves single-wire electricity transmission. The SWET system is characterized by low capital costs compared to a typical 3x400V line. Experience from the HEETII project will be used to build the system.
The system's transmission capacity will be 100 kW with an efficiency of at least 90%. Energy will be transmitted via a single high-voltage, high-frequency (HVHF) SWL line over a distance of at least 600 m, using the ground as the return conductor.
The SWET system consists of a resonant inverter that transfers energy to a single-wire high-voltage line via a resonant circuit and a transformer. At the other end of the line, the electricity is transferred to the 3x400V AC power grid via a transformer, rectifier, and inverter.
