Consolidated editions The IEC is now publishing consolidated versions of its publications. Multimeter Multimeters are undoubtedly the most common item of electrical test equipment in use. Retrieved from " https: He has a deep technical understanding of electrical engineering and is keen to share this knowledge. A beginner's guide to wand motions. This migration has already been largely completed, at least within the European Union. Motor starting and its associated problems are well-known to many people who have worked on large industrial processes.

Reference number IEC Information relating to this publication, including its validity, is available in the IEC Catalogue of publications see ic in addition to new editions, amendments and corrigenda.
The lower values in the first and second columns are voltages to neutral and the higher values are voltages between phases.
It excludes voltage transients, such as those due to system switching, and temporary voltage variations.
INTERNATIONAL STANDARD IEC 60038
Multimeters are undoubtedly the most common item of electrical test equipment in use. The object of the IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields.
NOTE 2 It is recognized that for technical and economic reasons additional voltages may be required for certain specific fields of application. Nominal values Nominal values Preferred Supplementary Preferred Supplementary V V V V 2,4 3 4 4,5 5 5 6 6 7,5 9 12 12 15 15 24 24 30 36 36 40 48 48 60 60 72 80 96 NOTE 1 Because the voltage of the primary and secondary cells is below 2,4 V, and the choice of the type of cell to be used in various applications will be based on properties other than the voltage, these values are not included in the table.
This article relies largely or entirely on a single source.
Add this document to saved. This publication shall not apply to standard voltages of components and parts used within electrical devices or items of equipment.
It is recommended that only one of the series should be used in any one country. Understanding Circuit Breaker Markings IEC is ieec circuit breaker standard and covers the marking of breakers in detail.
INTERNATIONAL STANDARD IEC
Your e-mail Input it if you want to receive answer. It is also recommended that only one of the two series of nominal voltages given for Series I should be used in any one country. For example, edition numbers 1. Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. It is recommended that in any one country only one value in the following groups should be used for the highest voltage for equipment: The relevant IEC ice committees may specify types of cells and related voltages for specific applications.
Steven McFadyen Steven has over twenty five years experience working on some of the largest construction projects.
The values indicated in parentheses should be considered as non-preferred values. The enumeration begins at kV and ends with kV. This page was last edited on 27 Augustat This publication shall not apply to voltages representing or transmitting signals or measured values. Please lec improve this article by introducing citations to additional sources.
A beginner's guide to wand motions. It is understood that, particularly for certain nominal system voltages, normal operation of equipment cannot be ensured up to this highest voltage for equipment, having regard to oec characteristics such as losses of capacitors, magnetizing current of transformers, etc.
Retrieved from " https: Click here to view the notes indexed by tag. For the utilization voltage range, in addition to the voltage variations irc the supply terminals, voltage drops may occur within the consumer's installations.
Voltage Levels to IEC 60038
Please assess the standard in the following categories, using the numbers: The highest voltage for equipment is the maximum value of the "highest system voltage" see 2. What happened to the cable notes? From Wikipedia, the free encyclopedia. This sixth edition supersedes the fifth edition of IECand now includes ic voltages below V a.
