Overview

EN 60358-2:2013 (IEC 60358-2:2013) specifies requirements for AC or DC single‑phase coupling capacitors connected between line and ground for power line carrier‑frequency (PLC) applications. It applies to coupling capacitors with a rated voltage greater than 1 000 V, where the low‑voltage terminal is either permanently earthed or connected to PLC equipment. The standard covers PLC frequency bands (typically 30 kHz to 500 kHz) and similar DC/AC applications at power frequencies (15 Hz to 60 Hz). This Part 2 supplements EN/IEC 60358‑1 (general rules) and should be used together with it.

Key Topics and Requirements

• Scope and service conditions: Defines intended use for coupling capacitors and carrier‑frequency accessories in overhead and cable power networks.
• Ratings and design: Requirements for rated voltage, mechanical and electrical design of coupling capacitors and associated PLC accessories (drain coils, voltage limitation devices).
• High‑frequency electrical characteristics: Measurement of high‑frequency capacitance and equivalent series resistance (ESR); limits for stray capacitance and stray conductance at the low‑voltage terminal.
• Testing regimes:
  • Routine tests (tightness for liquid‑filled equipment, electrical routine checks).
  • Type tests (high‑frequency capacitance/ESR, stray capacitance, tests on drain coils and voltage limitation devices including impulse tests).
  • Special tests and temperature‑rise checks for windings.
• Marking and documentation: Mandatory marking of capacitors and carrier‑frequency accessories for safe installation and identification.
• Compatibility with PLC transmission requirements: Transmission-related specifications are referenced to IEC 60481 (coupling devices for power line carrier systems).

Applications

• Enabling power line carrier (PLC) communications by coupling high‑voltage power lines to PLC equipment.
• Use in substations, overhead lines and power distribution networks where line‑to‑earth coupling is required for PLC signalling.
• Design and production of coupling capacitors, capacitor dividers and associated carrier‑frequency accessories intended for utility and industrial PLC systems.

Who Should Use This Standard

• Manufacturers and designers of coupling capacitors and PLC accessories.
• Power utilities specifying equipment for PLC signalling and line monitoring.
• Test laboratories performing type, routine and special tests on coupling devices.
• Certification bodies, procurement teams and engineers responsible for installation, maintenance and safety of PLC coupling equipment.

Related Standards

• EN/IEC 60358‑1 (General rules for coupling capacitors and capacitor dividers)
• IEC 60481 (Coupling devices for power line carrier systems)
• IEC 60060‑1 / IEC 60060‑2 (High‑voltage test techniques)

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.

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
