24、transmission medium for supporting Distribution Automation and Home and Building Electronic Systems (HBES). In order to avoid unwanted interference among mains communication equipment transmitting on low voltage networks, a suitable device called “decoupling filter“ may be installed either on the pu
25、blic supply network or within installations in consumers premises. Decoupling filter is a generic name given, for example, to incoming filter, impedance filter, segmentation filter. This decoupling filter may be incorporated in a more complex device where optional coupling functions are included (re
26、f. Figure 1) according to signal propagation methods described in the informative annex A. The decoupling filter may be used: a) to limit the transmission area of wanted signals to the area in which the mains communication system operates. b) to reduce unwanted signals coming from the other side of
27、the mains port. c) to allow simultaneous communication on both sides of the filter. d) to set a suitable impedance to the mains power ports at the signalling frequency. e) to provide a return path for the signal when needed (e.g. common mode propagation). A decoupling filter may perform all the func
28、tions listed above or some of them.

29、- Filter combined with other functions- 5 - EN 50065-4-1:2001 1 Scope This standard applies to decoupling filters installed on the low voltage mains network and operating in the frequency range 3 kHz to 148,5 kHz on low voltage mains network. It does not apply to general purpose filters for EMI supp
30、ression. It does not apply to protocol dependant devices except physical layer (frequency). It does not apply to filters incorporated in household equipment for example: washing machines and coffee machines. It specifies the impedance and the transfer function definitions, requirements and test meth
31、ods of the decoupling filter and some other requirements for example Voltage Drop, Leakage Current and Form Factor. The impedance and the transfer function are referred to the decoupling filter mains power ports (ref. Figure 1). The use of the decoupling filter is considered optional; additional rul
32、es or obligations may exist that are outside the scope of this standard. The safety requirements related to decoupling filters are not covered in this standard. They are covered in an other part of the EN 50065 set of standards 2 Normative references This European Standard incorporates by dated or u
