Nowadays, when increasing efficiency is important and cost saving is in the first place, we try to use our infrastructure to its limits. The overloaded wire networks cannot stop the negative effect of technologies on each other. This is why it is important for us to use and improve technologies that will meet the requirements of our modern age by regulating noise emission and immunity.
My task is to examine the effect of non-linear devices in the range of 2-150 kHz and their effect on the PLC. I also investigated the present situation of the relevant standards and the processes involved in this matter.
I used the equipment available in the laboratory, namely the inverter and the PLC ready devices. I measured the effect of the inverter in the 2-150 kHz frequency range as well as the PLC data transfer rate (upload and download) without the mentioned devices attached and later on with the devices attached. My measurements took place in the laboratory within a short period of time, so that the effect of the network that is changing during the day would be minimal.
My task is important, as we have to explore the factors that have major effect on emission and immunity, so that we could change them to reach a better efficiency of the technology.
