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

Scope

This document applies to incoming filters used to control the coupling of signals between the utility area and the consumer area, as illustrated in Figure 1.
This document defines:
- the minimum impedance in the relevant frequency band(s) at both utility port and consumer port,
- the minimum attenuation of unwanted signals transmitted from the utility side to the consumer side and vice versa.
This document applies to incoming filters designed for single or multiphase installations.
