Definitions

  • the low frequency energy from the substation is directly conveyed by supply lines to the premises b1, b2.
  • the transport of this energy because it is low frequency energy, is much easier and causes very much less loss than that of radio frequency energy between the central building and the antennas of the center according to Figure 1; in fact this transport can be carried out by flexible cables laid on the ground or buried whereas, in the case of figure 1, the transport of the radiofrequency energy was done by symmetrical lines, suspended at a height of several meters au- above the ground thanks to posts and insulators.
