IEC 60038 STANDARD VOLTAGES PDF

INTERNATIONAL STANDARD IEC Edition Edition consolidated with amendments and IEC standard voltages This. The standard aims to consolidate AC and traction voltages within the industry and defines the following bands: band 1 – A.C. systems V to. IEC IEC standard voltages. a.c. and d.c. equipment having nominal voltages below V a.c. or below V d.c., the a.c. voltages being intended.

NOTE 1 It is recommended that in any one country the ratio between two adjacent nominal voltages should be not less than two.

Three phase systems are derived from three separate windings, either connected in delta or star wye. This publication shall not apply to voltages representing or transmitting signals or measured values. Relevant discussion may be found on the talk page.

It starts with me reading one of the Horrible Stanfard books with my son Groovy Greeks. The committee has decided that the contents of the base publication and its amendments 1 and 2 will remain unchanged until For the utilization voltage range, in addition to the voltage variations at the supply terminals, voltage drops may occur within the consumer’s installations.

The values indicated are voltages between phases. Copyright c myElectrical.

Voltage Levels to IEC 60038

From Wikipedia, the free encyclopedia. It is recommended that these values should not be used for new systems to be constructed in future. Consolidated editions The IEC is now publishing consolidated versions of its publications.

Steven McFadyen Steven has over twenty five years experience working on standarx of the largest construction projects. NOTE In the present table, the term “geographical area” may indicate a single country, a group of countries which agree to adopt the same voltage level, or a part of a very large country.

The highest voltage for equipment is the maximum value of the “highest system voltage” see 2. This utilization range should be taken into account by Product Committees.

Voltage Levels to IEC

It is recommended that only one of the two series should be used in any one country. There are two series, one from 3 kV up to 35 kV and another one from 4. The relevant IEC technical committees may specify types of cells and related voltages for specific applications.

The enumeration begins at kV and ends with kV. Any divergence between the IEC Standard and the corresponding national voltges regional standard shall be clearly indicated in the latter.
