VDE Art. No.: 0800936

This document applies to impedance filters in a mains communication system, intended for utility networks or household and similar fixed installations including residential, commercial and light industrial buildings.
These filters are used to set a suitable impedance, in the nominal frequency range of mains signalling system, at any point of the low voltage mains network where a low impedance equipment is connected, as shown in Figure 1, in order to allow reliable operation of the mains signalling system. Impedance filters can be used either in utility or consumer networks. They can also be used in conjunction with incoming filters and segmentation filters.
