Signalling on low-voltage electrical installations in the frequency range 3 kHz to 148.5 kHz. Low voltage decoupling filters - Segmentation filter Ingestion-build-141043 What is BS EN 61068-21 Scope This standard applies to segmentation filters in a mains communication system used for single or multiphase installations having a phase to neutral voltage not exceeding 250 V a. c. and a nominal current not exceeding 125 A, intended for household and similar fixed installation including residential, commercial and light industrial buildings and utility networks. These filters (see Figure 1) are used to control the coupling of signals between
