Power quality measurement in power supply systems - Part 1: Power quality instruments (PQI)

IEC 62586-1:2013 specifies product and performance requirements for instruments whose functions include measuring, recording and possibly monitoring power quality parameters in power supply systems, and whose measuring methods (class A or class S) are defined in IEC 61000-4-30. These requirements are applicable in single, dual- (split phase) and 3-phase a.c. power supply systems at 50 Hz or 60 Hz. These instruments can be used in the generation, transmission and distribution of electricity, for example inside a power station, substation or a distributed generator connection and at the interface point between the installation and the network, e.g. in order to check the compliance of the connection agreement between a network operator and the customer. These instruments are fixed-installed or portable. They are intended to be used indoors and/or outdoors. Devices such as digital fault recorders, energy/power meters, protection relays or circuit breakers may include power quality functions defined in 61000-4-30 class A or class S. If such devices are specified according to this standard, then this standard fully applies and applies in addition to the relevant product standard. This standard does not replace the relevant product standard.

POWER QUALITY MEASUREMENT IN POWER SUPPLY SYSTEMS –

Part 1: Power quality instruments (PQI)

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 62586-1 has been prepared by IEC technical committee 85:
Measuring equipment for electrical and electromagnetic quantities.
The text of this standard is based on the following documents:

INTRODUCTION
Electricity as delivered to the network users has several characteristics which are variable
and which affect its usefulness to the network user.
Power quality instruments on the market have different characteristics. This standard provides
a common system of references in order to facilitate their selection, comparison and
evaluation. This standard specifies a classification based on product performances,
environment and safety.
It is acknowledged that IEC 61000-4-30 is a basic EMC publication. Detailed guidance on
instrument performance, performance verification methods, additional influence quantities and
other similar information should, in general, be found in a product standard.
IEC 62586-1 is a product standard that refers to IEC 61000-4-30, IEC 61000-4-7 and
IEC 61000-4-15 for measuring methods. IEC 62586-2 specifies functional tests and
uncertainty requirements for instruments in the scope of IEC 62586-1.
IEC 62586-1 is therefore complementing basic EMC standards with environmental, safety and
performance requirements.

POWER QUALITY MEASUREMENT IN POWER SUPPLY SYSTEMS –

Part 1: Power quality instruments (PQI)



1 Scope
This part of IEC 62586 specifies product and performance requirements for instruments
whose functions include measuring, recording and possibly monitoring power quality
parameters in power supply systems, and whose measuring methods (class A or class S) are
defined in IEC 61000-4-30.
These requirements are applicable in single, dual- (split phase) and 3-phase a.c. power
supply systems at 50 Hz or 60 Hz.
These instruments can be used:
– in the generation, transmission and distribution of electricity, for example inside a power
station, substation or a distributed generator connection.
– at the interface point between the installation and the network, e.g. in order to check the
compliance of the connection agreement between a network operator and the customer.
NOTE 1 These instruments can also be used for other applications, e.g. inside commercial / industrial
installations especially where comparable measurements are needed (i.e. data centers or petrochemical plants).
These instruments are fixed-installed or portable. They are intended to be used indoors
and/or outdoors.
Devices such as digital fault recorders, energy/power meters, protection relays or circuit
breakers may include power quality functions defined in 61000-4-30 class A or class S. If
such devices are specified according to this standard, then this standard fully applies and
applies in addition to the relevant product standard. This standard does not replace the
relevant product standard.
NOTE 2 It is not the intent of this standard to address user interface or topics unrelated to device measurement
performance.
NOTE 3 The standard does not cover post-processing and interpretation of the data, for example with a dedicated
software.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and
are indispensable for its application. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any
