1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, the IEC publishes International Standards. Their preparation is

entrusted to technical committees; any IEC National Committee interested in the subject dealt with may

participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. The IEC collaborates closely with the International Organization

for Standardization (ISO) in accordance with conditions determined by agreement between the two

2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, an

international consensus of opinion on the relevant subjects since each technical committee has representation

3) The documents produced have the form of recommendations for international use and are published in the form

of standards, technical specifications, technical reports or guides and they are accepted by the National

4) In order to promote international unification, IEC National Committees undertake to apply IEC International

Standards transparently to the maximum extent possible in their national and regional standards. Any

divergence between the IEC Standard and the corresponding national or regional standard shall be clearly

5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

Requirements of IEC 61334-3-21 are applicable for phase-to-phase isolated capacitive

coupling devices for power-line carrier systems on distribution line carriers (DLC).

However, no international standard is available for the application of screen-to-earth intrusive

Furthermore the already standardised earthed capacitive coupling device for high voltage

power-line carrier systems as described by IEC 60481 is not suitable for the application of DLC

– from a technical point of view, network characteristics differ considerably from HV to MV

– from an economical point of view, the coupling device should have a price as low as

These considerations have led to the present standardisation of other coupling devices such as

the MV phase-to-earth capacitive coupling device and the screen-to-earth intrusive inductive

coupling device. Figures 1 and 2 show solutions for these devices. Additional solutions may

As other coupling devices are standardised, new parts to IEC 61334 will be added.

This part of IEC 61334 is applicable to MV phase-to-earth capacitive and screen-to-earth

intrusive inductive coupling devices for medium voltage (MV) distribution line carrier (DLC)

systems. Non-intrusive inductive coupling devices are not within the scope of this standard.

a) the efficient transmission/reception of carrier-frequency signals between the DLC

b) the safety of personnel and the protection of the low-voltage parts of the installation against

The object of this part of IEC 61334 is to establish definitions, requirements, methods of testing

and rated values for phase-to-earth capacitive and screen-to-earth intrusive inductive coupling

The following normative documents contain provisions which, through reference in this text,

constitute provisions of part of IEC 61334. For dated references, subsequent amendments to,

or revisions of, any of these publications do not apply. However, parties to agreements based

on this part of IEC 61334 are encouraged to investigate the possibility of applying the most

recent editions of the normative documents indicated below. For undated references, the latest

edition of the normative document referred to applies. Members of IEC and ISO maintain
