Developing a PLC module of electricity neter for AMR

In this paper, we developed a removable PLC module for electricity meter for AMR. The developed PLC module is compatible with Korea standard (KS) 4600-1 and consumes low power under 3 watts. We focused on suppressing noise which can be generated from a power supply, LC components, and several signal mismatches. Thus we can achieve long distance PLC communication with high robustness in terms of noise which is essence for digital electricity meter for AMR.
