IEC TR 61000-4-32:2002

Tue, 05 Nov 2024 20:01:36 +0000

Provides information about extant system-level high-altitude EMP (HEMP) simulators and their applicability as test facilities and validation tools for immunity test requirements. This report provides the first detailed listing of HEMP simulators throughout the worldand is the preliminary summary of this effort. It should be updated on a regular basis as the status of test facilities change. The main body of the report is a collection of datasheets describing 42 EMP simulators in 14 countries that are still operational or could be made available for use by the international community.

Tue, 05 Nov 2024 20:01:23 +0000

The purpose of this Technical Report is to describe the effects that have occurred during actual and simulated electromagnetic pulse testing throughout the world. These effects include those observed during the high-altitude nuclear tests conducted by the United States and the Soviet Union in 1962, and the HEMP simulator tests conducted by many countries during the years after atmospheric testing ended. In addition to direct effects, this technical report also contains information on HEMP coupling to "long lines" as it is important to verify that particular levels of currents and voltages can be induced by HEMP on these lines; this provides a basis for direct injection testing of electronic equipment. It should be noted that, in most cases, the electrical equipment tested or exposed did not contain the sensitive electronics in use today. Also it should be emphasized that all tests and exposures did not produce failure of the equipment; factors such as the geometry of the HEMP interaction and the electromagnetic shielding of the equipment are variables that can produce differing results. The description of these effects is intended to illustrate the seriousness of the possible effects of HEMP on modern electronic systems.

IEC 61000-4-30:201 5 defines the methods for measurement and interpretation of results for power quality parameters in a.c. power supply systems with a declared fundamental frequency of 50 Hz or 60 Hz. Measurement methods are described for each relevant parameter in terms that give reliable and repeatable results, regardless of the method's implementation. This standard addresses measurement methods for in-situ measurements. Measurement of parameters covered by this standard is limited to conducted phenomena in power systems. The power quality parameters considered in this standard are power frequency, magnitude of the supply voltage, flicker, supply voltage dips and swells, voltage interruptions, transient voltages, supply voltage unbalance, voltage harmonics and interharmonics, mains signalling on the supply voltage, rapid voltage changes, and current measurements. Emissions in the 2 kHz to 150 kHz range are considered in Annex C (informative), and over- and underdeviations are considered in Annex D (informative). Depending on the purpose of the measurement, all or a subset of the phenomena on this list may be measured. This third edition cancels and replaces the second edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
– the measurement method for current, previously informative, is now normative with some changes;
– the measurement method for RVC (rapid voltage change) has been added;
– the measurement method for conducted emissions in the 2 kHz to 150 kHz range has been added in informative Annex C;
– underdeviation and overdeviation parameters are moved to informative Annex D;
– Class A and Class S measurement methods are defined and clarified, while Class B is moved to informative Annex E and considered for future removal;
– measurement methods continue in this standard, but responsibility for influence quantities, performance, and test procedures are transferred to IEC 62586-2.

IEC 61000-4-23:2016

Tue, 05 Nov 2024 19:11:33 +0000

IEC 61000-4-23:2016(E) provides a protective devices test method for HEMP and other radiated disturbances. It is primarily intended for HEMP testing but can be applied to other externally generated radiated disturbances where appropriate. It provides a brief description of the most important concepts for testing of shielding elements. For each test, the following basic information is provided:
– theoretical foundation of the test (the test concepts);
– test set-up including outside-to-in and inside-to-out measurements;
– required equipment;
– test procedures;
– data processing.
This international standard does not provide information on requirements for specific levels for testing. Due to the available space, a transmitting antenna position outside the barrier has mainly been suggested. However, nowadays, many EMP protection facilities in practical use do not actually have enough space available outside the electromagnetic barrier due to physical constraints such as concrete walls or soil to allow the method described in IEC 61000-4-23:2000 (edition 1) to be applied correctly. From experience many facilities have available space for a 1 m separation or less only. Therefore, in many practical cases it is not possible to measure shielding effectiveness according to the test method of previous documents. The constructors for EMP protection facilities are also unwilling to build facilities with extra space for measurements with the transmitting antenna outside the barrier due to the great expense and inefficiency of the operational working area for new or existing buildings. This document provides additionally a method that allows the transmitting antenna to be placed inside the enclosure and the receiving antenna outside the barrier ('inside-to-out' method). Annex F includes test set-up and procedure examples. This second edition cancels and replaces the first edition published in 2000. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) updates to the shielding effectiveness (SE) test method in Clause 5;
b) a new Annex F describing methods for testing 'inside-to-out' has been added.

CAN/CSA-IEC 61000-4-30:16:2016 Edition

Tue, 05 Nov 2024 14:23:18 +0000

Preface

This is the third edition of CAN/CSA-IEC 61000-4-30, Electromagnetic compatibility (EMC) – Part 4-30: Testing and measurement techniques – Power quality measurement methods, which is an adoption without modification of the identically titled IEC (International Electrotechnical Commission) Standard 61000-4-30 (third edition, 2015-02). It supersedes the previous edition published in 2010 as CAN/CSAC61000-4-30 (adopted IEC 61000-4-30:2008).

Scope

This part of IEC 61000-4 defines the methods for measurement and interpretation of results for power quality parameters in a.c. power supply systems with a declared fundamental frequency of 50 Hz or 60 Hz.

Measurement methods are described for each relevant parameter in terms that give reliable and repeatable results, regardless of the methods implementation. This standard addresses measurement methods for in-situ measurements.

Measurement of parameters covered by this standard is limited to conducted phenomena in power systems. The power quality parameters considered in this standard are power frequency, magnitude of the supply voltage, flicker, supply voltage dips and swells, voltage interruptions, transient voltages, supply voltage unbalance, voltage harmonics and interharmonics, mains signalling on the supply voltage, rapid voltage changes, and current measurements. Emissions in the 2 kHz to 150 kHz range are considered in Annex C (informative), and over- and under deviations are considered in Annex D (informative). Depending on the purpose of the measurement, all or a subset of the phenomena on this list may be measured.

NOTE 1 Test methods for verifying compliance with this standard can be found in IEC 62586-2.

NOTE 2 The effects of transducers inserted between the power system and the instrument are acknowledged but not addressed in detail in this standard. Guidance about effects of transducers can be found IEC TR 61869-103.

Préface

Ce document constitue la deuxième édition de la CAN/CSA-C61000-4-30, Compatibilité électromagnétique (CEM) – Partie 4-30 : Techniques d’essai et de mesure – Méthodes de mesure de la qualité de l’alimentation. II s’agit de l’adoption, avec exigences propres au Canada, de la norme CEI (Commission Électrotechnique Internationale) 61000-4-30 (deuxième édition, 2008-10), qui porte le même titre. Cette norme remplace l’édition précédente publiée en 2004 qui portait la désignation CAN/CSA-CEI/IEC 61000-4-30 (norme CEI/IEC 61000-4-30:2003 adoptée).

Domaine d’application

La présente partie de la CEI 61000-4 définit les méthodes de mesure des paramètres de qualité de l’alimentation des réseaux à courant alternatif 50/60 Hz et la façon d’interpréter les résultats.

Les méthodes de mesure sont décrites pour chaque paramètre applicable en des termes qui fournissent des résultats fiables et répétitifs indépendamment de l’implémentation de la méthode. La présente norme porte sur les méthodes de mesure destinées aux mesures in situ.

La mesure des paramètres couverts par la présente norme se limite aux phénomènes en tension susceptibles de se propager sur un réseau d’énergie électrique. Les paramètres de qualité de l’alimentation pris en compte dans la présente norme sont la fréquence, l’amplitude de la tension d’alimentation, le papillotement («flicker»), les creux et les surtensions temporaires d’alimentation, les coupures de tension, les tensions transitoires, le déséquilibre de tension d’alimentation, les harmoniques et interharmoniques de tension, les signaux transmis sur la tension d’alimentation et les variations rapides de tension. En fonction de L’objet de la mesure, les mesures peuvent porter soit sur une partie des phénomènes de cette liste, soit sur l’ensemble.

NOTE 1 Des informations sur les paramètres en courant se trouvent dans les Articles A.3 et A.5.

La présente norme fournit des méthodes de mesure et des exigences de performances appropriées sans fixer de seuils.

Les effets des transducteurs lorsqu’ils sont placés entre le réseau et l’appareil de mesure sont pris en compte mais non traités en détail dans la présente norme. Les précautions à prendre pour installer des appareils de mesure sur des circuits sous tension sont indiquées dans la présente norme.

NOTE 2 Des recommandations sur les effets des transducteurs se trouvent dans la CEI 61557-12.
