<p>The method involves injecting a powerline communication signal to a secondary (BT) of a transformer between two phase conductors, in a symmetric mode using a circuit comprising a power line adapter, a modem and a microprocessor. The symmetric mode signal is converted to a common mode signal using a powerline communication signal converter situated near a user service area, and the user is serviced by the common mode signal. An independent claim is also included for a device for injecting a powerline communication signal in a three-phase cable network transporting electrical energy.</p> |
