64 Introduction
65 Electrical networks, in spite of being a difficult medium for data communication due to signal
66 attenuation, noise level and coupling side impedance, are considered as an important transmission
67 medium for supporting Distribution Automation and Home and Building Electronic Systems (HBES).
68 In order to avoid unwanted interference among mains communication equipment and/or low
69 impedance issues on low voltage networks, a suitable device called “decoupling filter” may be installed
70 either on the public supply network or within installations in consumers' premises.
71 A decoupling filter is a generic name given to incoming filters, impedance filters, segmentation filters
72 and phase couplers.
73 The decoupling filter may be used:
74 a) to limit the transmission area of wanted signals to the area in which the mains communication
75 system operates.
76 b) to reduce unwanted signals coming from the other side of the mains port.
77 c) to allow simultaneous communication on both sides of the filter.
78 d) to set a suitable impedance to the mains power ports at the signalling frequency.
79 e) to provide a return path for the signal when needed (e.g. common mode propagation).
80 A decoupling filter may perform all the functions listed above or some of them.

84 1 Scope
85 This document applies to decoupling filters installed on the low voltage mains network and operating in
86 the frequency range 3 kHz to 148,5 kHz.
87 It does not apply to EMI suppression filters incorporated in household equipment or other general
88 electric equipment.
89 It specifies the definitions, requirements and test methods of the functional, technical and
90 environmental characteristics of the decoupling filter, e.g. impedance, transfer function, voltage drop,
91 leakage current and power dissipation.
92 The impedance and the transfer function are referred to the decoupling filter mains power ports
93 (see Figure 1).
