1 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 two areas of a mains communication system
The standard defines
• the minimum impedance in the relevant frequency range(s) at both ports,
• the minimum attenuation of signals transmitted between port

3 Classification
Segmentation filters are used to separate one powerline communication system that operates in one operating frequency band, in several independent segments
The combination of the appropriate segmentation filter in conjunction with an incoming filter and/or with an impedance filter shall be made according to local regulations
3.1 Type 1: Asymmetrical filter
This filter has one "supply backbone port" and one "segment port" The "supply backbone port" and the "segment port" have different impedance characteristics in the operating frequency band and shall not be inverted Communication may not be possible on the “supply backbone port”
3.2 Type 2: Symmetrical filter
This filter has two "segment port" Both "segment ports" have the same impedance characteristics at the operating frequency band and may be inverted Usually the ports of a symmetrical segmentation filter are connected to different segments of one mains communication system

• the attenuation within these bands
4.2 Electrical characteristics at mains frequency
4.2.1 Over voltage
The filter shall meet the requirements in accordance with 15.2 of EN 50065-4-2 with
• overvoltage category III for segmentation filters used on the consumer network,
• overvoltage category IV for segmentation filters used on the utility network
4.2.2 Immunity
Immunity is specified as follows:
• according to EN 50065-2-1 for segmentation filters in residential, commercial and light industrial environments;
• according to EN 50065-2-2 for segmentation filters in industrial environments;
• according to EN 50065-2-3 for segmentation filters in the utility networks
4.3 Electrical characteristics at signalling frequency
4.3.1 Operating frequency range
The operating frequency range is a (reduced) frequency range the filter is designed for in the relevant band:
• it shall be in the frequency band 3 kHz to 95 kHz for utility segmentation filters;
• it shall be in the frequency band 95 kHz to 148,5 kHz for consumer segmentation filters
The manufacturer shall specify the operating frequency range
4.3.2 Impedance
4.3.2.1 Asymmetrical segmentation filter (type 1)
On the segment port of the filter, when measured in the operating frequency range specified by the manufacturer fmin to fmax,, according to 6.1 of EN 50065-4-1, the modulus value of the impedance shall
be greater than 10 Ω
On the “supply backbone port” there is no requirement
4.3.2.2 Symmetrical segmentation filter (type 2)
On both ports of the filter, when measured in the operating frequency range specified by the manufacturer fmin to fmax,, according to 6.1 of EN 50065-4-1, the modulus value of the impedance shall
be greater than 10 Ω

4.3.3 Transfer function
The transfer function and the measuring methods are defined in 6.2 of EN 50065-4-1
In the operating frequency range specified by the manufacturer fmin to fmax, the segmentation filter shall provide an attenuation specified by the manufacturer, in each direction when the filter is loaded with
