Clause 1 of IEC 60358-1:2012 is applicable with the following additions: This part of the IEC 60358 series applies to AC or DC single-phase coupling capacitors, with rated voltage > 1 000 V, connected between line and ground with a low voltage terminal either permanently earthed or connected to a device for power line carrier-frequency (PLC) applications at frequencies from 30 kHz to 500 kHz or similar applications (DC or AC) at power frequencies from 15 Hz to 60 Hz. The transmission requirements for coupling devices for power line carrier (PLC) systems are defined in IEC 60481.

COUPLING CAPACITORS AND CAPACITOR DIVIDERS –

FOREWORD

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

all national electrotechnical committees (IEC National Committees). The object of 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, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). 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. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

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

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

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 60358-2 has been prepared by IEC technical committee 33: Power

capacitors and their applications.
The text of this standard is based on the following documents:
FDIS Report on voting
33/531/FDIS 33/537/RVD

Full information on the voting for the approval of this standard can be found in the report on

voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all parts in the IEC 60358 series, published under the general title Coupling

and its amendments. It was established on the basis of the first edition (2012) of that

standard.
This Part 2 supplements or modifies the corresponding clauses in IEC 60358-1.

When a particular subclause of Part 1 is not mentioned in this Part 2, that subclause applies

as far as is reasonable. Where this Part 2 states “addition” or “replacement”, the relevant text

in Part 1 is to be adapted accordingly.

For additional clauses, subclauses, figures, tables or annexes, the following numbering

system is used:

– subclauses, tables and figures which are additional to those in Part 1 are numbered

starting from 200;
– additional annexes are lettered AA, BB etc.

– as the notes are integrated into the clauses, their numbering starts from 1 as usual.

The committee has decided that the contents of this publication will remain unchanged until

the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data

related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

---------------------- Page: 14 ----------------------
SIST EN 60358-2:2014
60358-2 © IEC:2013 – 9 –
6.200.2 Design requirements for carrier-frequency accessories
6.200.2.1 General

The carrier-frequency accessories, comprising a drain coil and a protective device, shall be

connected between the low voltage terminal of the coupling capacitor and the earth terminal.

The connections are typically as shown in Figure A.1.
The requirements for the complete coupling device are specified in IEC 60481.
6.200.2.2 Drain coil
The drain coil shall be designed in such a way, that:

a) for an AC application, the impedance should be as low as possible and in no case exceed

20 Ω at power frequency;

for a DC application, no standard value is defined; manufacturer and purchaser shall

define the impedance value;
b) the current-carrying capability at power frequency is as follows:

– continuous operation: rated current of capacitor, but not less than 1 A r.m.s.;

– short-time current: 30 A r.m.s. for 0,2 s;

c) the drain coil shall be able to withstand a 1,2/50 μs impulse voltage whose peak value is

twice the value of the impulse spark voltage of the voltage limitation device, but the

minimum value should be 10 kV peak (see 10.201.2.2)

d) for a drain coil with iron core, the insulation between winding and iron core shall support

3 kV for 60 s (see 9.2.200.2.1.3).

e) If the maximum fundamental frequency current of the capacitor is higher than 1 A, the

continuous operation current for the drain coil should be increased accordingly

f) for a DC application, the grading current of the coupling capacitor shall not saturate the

drain coil.
6.200.2.3 Voltage limitation device

A lightning arrester shall be connected as directly as possible between the low voltage

terminal of the coupling capacitor and the earth terminals and shall be capable of protecting

the coupling device and the carrier-frequency connection.

For AC applications: The AC protection level voltage U at power frequency shall be greater

than 10 times the maximum AC voltage across the drain coil during rated operation

conditions.
The voltage U is given by the following formula:
U ≥ 10⋅ F ⋅ ⋅(2⋅π ⋅ f ) ⋅ C ⋅ L
PL V R R D
where
L is the value of the drain coil in henry;
F is the voltage factor according to IEC 60358-1:2012, Table 2.

NOTE 1 Arresters of the air-gap type or those of the non-linear resistor type are used.

Example:
a) power-frequency withstand test voltage:
– air-gap arrester: 2 kV r.m.s.,
– arrester with spark-gap: rated voltage: approx. 1 kV r.m.s.
---------------------- Page: 15 ----------------------
SIST EN 60358-2:2014
– 10 – 60358-2 © IEC:2013
b) impulse withstand voltage:

– air-gap arrester and arrester with spark-gap: at test impulse voltage of about 4 kV peak with a wave shape

8/20 μs the arrester are able to sustain the peak current of at least 5 kA.

NOTE 2 It is desirable that the arrester be capable of sustaining a power frequency current of at least 5 kA r.m.s.

for a period of 0,2 s while ensuring, even if damaged, that the other parts of the coupling device remain adequately

protected.
For DC applications:
The DC protection level voltage U shall be:
U ≥ 3,5 kV DC
NOTE 3 3,5 kV coming from 2,5 kV AC × √2.
7 Test conditions
