Filter for systems of PLC communication on low voltage electric networks,

摘要

Summary? Filter for systems of PLC communication on low voltage electric networks? The present invention consists of a device, applies to the area of electric energy.Specifically, in electrical networks of low - voltage used as the medium for transmission of communication signals, through the technology PLC (power line carrier).The device performs the function of a low pass filter, which allows the flow of electric power in low frequency (50 Hz or 60 Hz, for example) and, at the same time,It blocks the flow of communication signals.This filter can perform various functions in a network, PLC, such as: (I) to create two or more networks PLC from a same electrical network.Through the segmentation of the passages used by a set of transceivers PLC; (II) prevent interfering signals generated by a given load reaches the network PLC; (III) prevent signsPLC are mitigated by low impedance loads installed in the electrical network (e.g., a bank of capacitors).
