(Main)Signalling on low-voltage electrical installations in the frequency range 3 kHz to 148,5 kHz -- Part 2-3: Immunity requirements for mains communications equipment and systems operating in the range of frequencies 3 kHz to 95 kHz and intended for use by electricity suppliers and distributors
Signalling on low-voltage electrical installations in the frequency range 3 kHz to 148,5 kHz -- Part 2-3: Immunity requirements for mains communications equipment and systems operating in the range of frequencies 3 kHz to 95 kHz and intended for use by electricity suppliers and distributors
This standard applies to electrical equipment using signals in the frequency range 3 kHz to
95 kHz to transmit or receive information on low voltage electrical systems, for electricity
suppliers and distributors. In the case of equipment which includes functions other than the
transmission or reception of information on low voltage electrical supplies, this standard applies
only to that part of the equipment intended for such transmission or reception of information.
Other parts of the equipment shall comply with the immunity standard or standards relevant to the
functions of those other parts. In the event of tests being specified in those other standards of a
different severity and where the construction of the equipment is such that the functions cannot
be tested separately, the higher severity shall apply to all affected functions.
The object of this standard is to limit mutual influence between mains communication equipment
and systems (MCES) operating in different frequency bands as defined in EN 50065-1 and to
contribute to ensuring electromagnetic compatibility in general. It specifies essential immunity
requirements and test methods, including those tests which are to be performed during typetesting
of MCES on low-voltage installations, for electromagnetic interference in general and
more specific interference coming from other MCES. It therefore defines the immunity test
requirements for apparatus in relation to continuous and transient disturbances, both conducted
and radiated, and electrostatic discharges. Test requirements are specified for each port
considered.
This standard gives limits which are applicable to products operating in the public supply network,
operated by electricity utilities. The levels do not however cover extreme cases which may occur
in any location but with a low probability of occurrence. In special cases situations will arise where
the level of disturbances may exceed the levels specified in this standard e.g. where a hand-held
transmitter is used in proximity to an apparatus. In these instances special mitigation measures
may have to be employed.
It does not specify immunity between mains communication systems operating in the same band
(as defined in EN 50065-1) or immunity to signals originating from power line carrier systems
operating on high or medium voltage networks.
Safety considerations are not included in this standard.

Foreword
This European Standard was prepared by SC 205A, Mains communicating systems, of Technical
Committee CENELEC TC 205, Home and Building Electronic Systems (HBES).
The text of the draft was submitted to the Unique Acceptance Procedure and was approved by
CENELEC as EN 50065-2-3 on 2001-09-01.
The following dates were fixed:
- latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2003-08-01
- latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2004-08-01
This part of this standard defines limits and test methods for the immunity of mains
communication equipment and systems (MCES) operating in the range of frequencies from 3 kHz
to 95 kHz and intended for use by electricity suppliers and distributors. Immunity requirements for
similar equipment intended for operation in residential, commercial and light industrial
environments are given in Part 2-1 of this standard. Immunity requirements and tests applicable
to similar equipment intended for operation in industrial environments are given in Part 2-2 of this
standard. For MCES intended to be operated by utilities in the frequency range 3 kHz to 95 kHz,
with lower immunity requirements than specified in this Part 2-3, the specifications of Part 2-2 or
Part 2-1 may be applied.
These tests and limits represent essential electromagnetic compatibility and immunity
requirements for the environment according to the scope. Not all known disturbances have been
included for testing purposes which have been limited to those disturbances known to be critical
for the operation of such equipment including specific MCES disturbances such as conducted
narrow band.
The immunity requirements have been selected to ensure an adequate level of immunity for
MCES for use by electricity utilities. The levels do not however cover extreme cases which may
occur in any location but with an extremely low probability of occurrence.
NOTE This standard takes into account EN 50082-2, the generic immunity standard for the industrial environment,
from which much of the material is taken, but considering also the specific requirements for MCES in utilities’
environment. However the nature of MCES is such that the performance criteria given in clause 5 of this standard differ
from those given in EN 50082-2, particularly regarding the recovery of equipment following a disturbance. For clarity
and completeness all the affected sections of EN 50082-2 are therefore repeated in this part.
Annexes designated "normative" are part of the body of the standard.
In this standard, annex A is normative.

4 Description of locations
The environments encompassed by this standard are any locations in the public supply low
voltage (LV) network both indoor and outdoor. Apparatus covered by this standard is not intended
to be connected to a power network supplied from a high or medium-voltage transformer
dedicated to the supply of an installation feeding manufacturing or similar plant. This standard
applies to apparatus intended to operate in any location where electricity utilities’ MCES are
operated. Thus it applies to equipment installed at the boundary of a property, e.g. at the
metering point, and equipment installed at the LV side of a distribution transformer, and any
connected point between.
5 Performance criteria
For the purposes of the tables the performance criteria are:
A : the MCES continues to operate as intended (e.g. transmission, reception) within the
performance limits specified by the manufacturer. No change of actual operating state or
stored data is allowed;
---------------------- Page: 7 ----------------------
– 7 – EN 50065-2-3:2003
B : a temporary degradation or loss of function or performance is permitted during the
disturbance provided the equipment automatically resumes normal operation following the
removal of the disturbance. The time behaviour for this resumption of normal operation
shall be as specified in the MCES manufacturer's specification. No change of actual
operating state or stored data is allowed;
C : a temporary
