Nowadays there is a large amount of data that flows through the power line, the frequency used for the transmission of these data are regulated by different international standards, the frequencies of low bandwidth which we will try in this project, are among the 3 kHz. and 148, 5 kHz. corresponding to the legislation of the CENELEC EN 50065 Standard.
The problem to be solved, from a general point of view, is the possible intrusion by coincidence of fundamental frequencies, in many cases generated by accident, and can be occasionally generated expressly.
The CBF filters manufactured by EMIKON, counteract the possibility of the above-mentioned intrusion, that as we can see, must give a bidirectional solution, protecting the passive object (domestic, industrial, professional, etc.), as well as the active (the remote measurement module, remote control, automation control system, etc).
At the same time, must be solved the "in situ" measurement of these frequencies, both in its power and its frequency, to insert at the appropriate point, the discriminatory and canceling device of these disturbing and generating the above-mentioned intrusion signals.
