Abstract :
It is known that frequency converters generate both conducted and radiated noise that spreads out to the low-voltage distribution network and disturbs victim devices. Nowadays, it is also possible to utilize the low-voltage motor power cable between a frequency converter and an electric motor as a medium for data transmission. In this study, conducted noise propagation generated by the data transmission is measured and analyzed in the frequency-domain.
