Abstract

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. [Figure 1 - The application of incoming filter]
