3、 EN 60038:2011 as a British Standard. However, attention is drawn to the fact that during the development of this European Standard, the UK committee voted against its approval as a European Standard.BS EN 60038 specifies standard voltage values which are intended to serve as preferential values for

The reference values contained within this standard do not replace or modify the values given in product standards.It has been developed from the IEC Standard IEC 60038.BS EN 60038 is therefor

24、 HD 472 S1:1989 + corrigendum February 2002 + A1:1995. In this standard, the common modifications to the International Standard are indicated byThe main common modifications to IEC 60038:2009 are the following. All references to 60 Hz are removed in the European Standard (reason: 60 Hz is not used i
25、n Europe for a.c. electric systems). The “in some countries“ notes related to non-CENELEC countries are removed. The value of 100 kV as highest voltage for equipment corresponding to the value of 90 kV as nominal system voltage is added to Table 4 (reason: this value already exists in EN 62271-1 and
26、 is widely used in French transmission systems). Sentences containing recommendations are generally put in notes. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and CENELEC shall not be held responsible for identifying any or
27、 all such patent rights. tags .BS EN 60038:2011 EN 60038:2011 (E) 4 CENELEC STANDARD VOLTAGES 1 Scope This publication applies to a.c. transmission, distribution and utilization systems and equipment for use in such systems with a standard frequency of 50 Hz having a nominal voltage above 100 V; a.c
28、. and d.c. traction systems; a.c. and d.c. equipment having nominal voltages below 120 V a.c. or below 750 V d.c., the a.c. voltages being intended (but not exclusively) for 50 Hz applications;batteries (from primary or secondary cells), other power supply devicesequipment (including industrial and
29、communication), and appliances. NOTE Z1 Only standard frequency 50 Hz is used in Europe for public a.c. transmission and distribution systems. For systems and equipment at 60 Hz, see IEC 60038. This publication does not apply to voltages representing or transmitting signals or measured values. This
30、publication does not apply to standard voltages of components and parts used within electrical devices or items of equipment. This publication specifies standard voltage values which are intended to serve as preferential values for the nominal voltage of electrical supply systems, and as reference v
31、alues for equipment and system design. NOTE 1 Two main reasons have led to the values specified in this standard: The values of nominal voltage (or highest voltage for equipment) specified in this standard are mainly based on the historical development of electrical supply systems throughout the wor
32、ld, since these values turned out to be the most common ones, and have achieved worldwide recognition; The voltage ranges mentioned in this standard have been recognized to be the most appropriate ones as a basis for design and testing of electrical equipment and systems. NOTE 2 It is nevertheless t
33、he task of system and product standards to define appropriate testing values, testing conditions and acceptance criteria. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undate

42、or example, EN 60335-1 and EN 60071 ), the term “voltage range“ has a different meaning.

44、ment The nominal voltage of an a.c. system in the range from 100 V to 1 000 V should be selected from the values given in Table 1. Table 1 AC systems having a nominal voltage between 100 V and 1 000 V inclusive and related equipment Three-phase four-wire or three-wire systems aNominal voltage (at 50
45、 Hz) bV 230 230/400 400/690 1 000 a The three-phase four-wire systems include single-phase circuits (extensions, services, etc.) connected to these systems. b The lower values are voltages to neutral and the higher values are voltages between phases. When one value only is indicated, it refers to th
46、ree-wire systems and specifies the voltage between phases. Voltages in excess of 230/400 V are intended for heavy industrial applications and large commercial premises. Concerning supply voltage range, under normal operating conditions, the supply voltage should not differ from the nominal voltage o
47、f the system by more than 10 %. For the utilization voltage range, in addition to the voltage variations at the supply terminals, voltage drops may occur within the consumers installations. For more information, see HD 60364-5-52 . This utilization voltage range should be taken into account by produ
