The standard aims to consolidate AC and traction voltages within the industry and defines the following bands:. This utilization range should be taken into account by Product Committees. 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 voltage-sensitive characteristics such as losses of capacitors, magnetizing current of transformers, etc.

Reference number IEC It starts with me reading one of the Horrible History books with my son Groovy Greeks. Views Read Edit View history. In such cases, the relevant recommendations must specify the limit to which the normal operation of stahdard equipment can be ensured. Q5 This standard meets my needs: Our IEE cable sizing was wrote a few years ago and had become rough around the edges.

Steven McFadyen Steven has over twenty five years experience working on some of the largest construction projects. NOTE 1 The highest voltage for equipment is indicated for nominal system voltages higher than 1 V only.


Their preparation 60308 entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work.


Comments are closed for this post: Various techniques exist to enable the correct selection of batteries for UPS applications. If you have some expert knowledge or experience, why not consider sharing this with our community. Computer Max-f Fast power factor regulator Static.

NOTE 2 It is understood that the equipment to be used in systems having nominal voltage not exceeding 1 V should be specified with reference to the nominal system voltage only, both for operation and for insulation. Any divergence between the IEC Standard and the corresponding national or regional standard shall be clearly indicated in the latter. Review of LR circuits.

Voltage Levels to IEC 60038

The IEC shall not be held responsible for identifying any or all such patent rights. A lot of research has been conducted He has a deep technical understanding of electrical engineering and is keen to share this knowledge.

The voltagse IEC technical committees may specify types of cells and related voltages for voltagez applications. Copyright c myElectrical. Each winding can be treated separately, leading Please help improve this article by introducing citations to additional sources. 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.

List of International Electrotechnical Commission standards. Articles needing additional references from March All articles needing additional references Use British English Oxford spelling from January The system consists of a set of units and prefixes Documents Flashcards Grammar checker.


When one value only is indicated, it refers to three-wire systems and specifies the voltage between phases.


Electric power distribution IEC standards Electrical wiring. View 0 Comments old system. Arrows were mentioned which lead to the discussion of the bodkin Please assess the standard in the following categories, using the numbers: International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. The enumeration begins at kV and ends with kV.

This migration has already been largely completed, at least within the European Union. Enter the exact number of the standard: Relevant discussion may be found on the talk page.

Three phase systems are derived from three separate windings, either connected in delta or star wye. Q2 Please tell us in what capacity ies you bought the standard tick standarx that apply. I thought it was time to give the tool a service. On-line information is also available on recently issued publications, withdrawn and replaced publications, as well as corrigenda.

The procedure described below is one of the more common. The highest voltage for equipment is the maximum value of stajdard “highest system voltage” see 2. It is recommended that only one of the two series should be used standaed any one country.
