Abstract

Influence to electromagnetic environment has been studied for power line communication (PLC). Longitudinal conversion loss (LCL) and input impedance are important parameters to evaluate the influence. Indoor AC mains line is modeled considering with typical conditions of Japanese house. The modeled line and electric equipment are presented with 4-port F-matrixes. The parameters of 4-port F-matrix are determined from calculation and measurement. Using this model, the input impedance and the LCL are calculated. The analysis model is examined by a simple network, and the results show that the calculation values almost agree with the measured values. The input impedance and the LCL are investigated for actual AC mains line, and the measured results almost agree with the calculated value.
