Cable and Phase Identification based on Power Line Communication

Phase and cable identification is a challenging issue. Power-line communication technology is applied to identify cable and phase of power distribution systems. Power cable circuits have only a limited ability to carry higher frequencies. Typically transformers prevent propagating the higher frequency carrier signal. The proposed method uses the limited propagation ability to identify the cable as well as the phase. A new cable and phase identification system is designed and implemented. The system consists of a transmitter and a receiver with power-line communication module. Some experiments are conducted to verify the theoretical concepts in a commercial building. Also some simulations are done to help and understand the concepts by using Simulink simulator. It can extend the application area of power-line communication.
