Abstract

It has been shown that power line communication (PLC) is a feasible method for data transmission between a low-voltage (LV) motor and a frequency converter through the power cable. In this paper, attenuation and noise power spectrum of the communication channel are analyzed. The analysis is based on a laboratory test setup, laboratory measurements, simulation models, and known power spectral density (PSD) limits for commercial PLC equipment. Based on the analysis, a feasible frequency band for the motor cable communication with an inductive coupling circuit and without inverter output filter is proposed for different cable lengths covering typical lengths used in industrial LV motor drive applications.
