1 Scope

This European Standard applies to phase couplers in a mains communication system for 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

This European Standard applies to phase couplers used to control the coupling of communication signals between phases or sections of a mains communication system

A “phase coupler” may be used to achieve coupling between the phases of a multiphase installation,

or to provide bridging of signals around other system components

The standard defines

− the requirements to ensure a minimum coupling between the sections, and

− the requirements to ensure no change on the safety of the electrical installation

3 Definitions

For the purposes of this document, the terms and definitions given in EN 50065-1, EN 50065-4-1 and the following apply

3.1

phase terminal (PT)

connection to a phase conductor of the electrical installation in which the phase coupler is used

3.2

neutral terminal (NT)

connection to a neutral conductor of the electrical installation in which the phase coupler is used (may

or may not be provided)

3.3

mains frequency leakage current

4 Classification

The classification is made according to the “mains frequency leakage current” of the phase coupler

The filter shall meet the requirements given in Part 4-2: Low voltage decoupling filters – Safety requirements

4.1 Type 1 (standard type)

The coupling may be achieved with suitable capacitors Due to significant mains frequency leakage current the use of this type of phase coupler may be limited for safety reasons

The coupling may be achieved using a transformer

− according to EN 50065-2-1 for phase coupler in residential, commercial and light industrial environments,

− according to EN 50065-2-2 for phase coupler in industrial environments,

− according to EN 50065-2-3 for phase coupler in the utility networks

5.2.3 Mains frequency leakage current

The mains frequency leakage current, at the nominal voltage, is measured according to Figure 1 All terminals of the phase coupler are connected to the appropriate voltage, except one phase terminal that is connected to neutral through a gauge
