Transmitting between phases using PLC

Question: Can the PLC signal transmitted from one phase be received by a node on another phase?

 

Answer:

It is generally not possible for the PLC signal to cross the transformer due to the high impedance at the 132kHz carrier frequency. We would recommend using either capacitive or wireless phase couplers as described in the section “Different Electrical Phases” in the Application Note AN58825 “Cypress Powerline Communication Debugging Tools”.
