Brief description of the transmission of information signals cp1 hf in a support air or an underground cable conductors insulated with respect to the transport of a three phase electric energy, and coupling device for implementing it.

摘要

A power line communication system excites differential bipolar propagation mode on a four line (1-4) three phase (P1-3) overhead or underground cable (A) using a power line coupler (CPL) from a high frequency PLC generator (GCPL) connected between pairs of phases with one cable in each pair capacitively coupled.
