A Low Voltage Power Line Model for Broadband Communication
The influence of skin effect and proximity effect on resistance and inductance of per-unit-length is analyzed. Based on the finite element method, the resistance and inductance are solved by electromagnetic simulation software, and a method combining with open circuit impedance measurement to solve capacitance and conductance is proposed. The accuracy of the cable model is verified by testing, and the transmission characteristics of T network are emphatically analyzed. The modeling method has the advantages of accuracy and simplicity.
