Signalling on low-voltage electrical installations in the frequency range 3 kHz to 148,5 kHz Part 4-5: Low voltage decoupling filter - Segmentation filter

Scope

This document applies to segmentation filters in a mains communication system intended for utility networks or household and similar fixed installation including residential, commercial and light industrial buildings.
These filters are used to control the coupling of signals between two areas of a mains communication system, as illustrated in Figure 1.
This document defines in the relevant frequency range:
- the minimum impedance at both ports of the filter,
- the minimum attenuation of signals transmitted between the ports of the filter.
