In a typical PDF of IEC 60038 (particularly older editions like the 1983 or 1994 versions, or even the 2009 edition depending on formatting, font size, and annexes), page 103 commonly falls within one of two critical sections:
Searching for "iec 60038 standard voltages pdf 103" will lead you to two realities:
The standard explicitly refuses to harmonize traction voltages (railways) and shipboard voltages. So the 103 table is for buildings and general power distribution only. A train in Germany runs on 15kV 16.7 Hz – a voltage that doesn’t exist in IEC 60038.
That’s why the standard is called “Standard Voltages” – not “All Possible Voltages.”
If you want, I can sketch out what Table 103 looks like (the actual data layout) or explain why 110V DC is still listed despite being nearly extinct.
IEC 60038 Standard Voltages
The IEC 60038 standard provides a framework for the selection of standard voltages for use in electrical power systems. The standard defines the preferred voltages for both low-voltage and high-voltage applications.
Low-Voltage Standard Voltages
For low-voltage applications, the IEC 60038 standard recommends the following standard voltages: iec 60038 standard voltages pdf 103
These voltages are widely used in many countries, including Europe, Africa, and parts of Asia.
High-Voltage Standard Voltages
For high-voltage applications, the IEC 60038 standard defines the following standard voltages:
These high-voltage standard voltages are used for transmission and distribution of electrical power over long distances.
Benefits of Standardization
The IEC 60038 standard offers several benefits, including:
Conclusion
In conclusion, the IEC 60038 standard provides a framework for the selection of standard voltages for use in electrical power systems. The standard defines preferred voltages for both low-voltage and high-voltage applications, promoting interoperability, efficiency, and safety. The widespread adoption of this standard has facilitated the efficient transmission and distribution of electrical power globally. In a typical PDF of IEC 60038 (particularly

IEC 60038 is the international standard that establishes a set of standard nominal voltages used for alternating current (AC) and direct current (DC) electrical systems worldwide. It is categorized as a "horizontal standard," meaning its definitions provide a foundational baseline for many other technical committees and product standards. Core Objectives
The standard aims to harmonize electrical systems across borders to ensure:
Interoperability: Allowing electrical devices to work safely across different regions.
Design Efficiency: Providing reference values for equipment manufacturing and system design.
Operational Safety: Defining clear voltage ranges to prevent equipment damage and electrical hazards. Voltage Range Classifications
IEC 60038 organizes voltages into specific categories, primarily based on the risk of electrical shock or arcing: AC Voltage (Vrms) DC Voltage (V) Extra-Low Voltage (ELV) Low Voltage (LV) 50 – 1,000 V 120 – 1,500 V High Voltage (HV) Key Nominal Voltages (AC Systems)
The standard specifies "preferential values" for various systems: Low-Voltage (LV) Systems (100 V to 1,000 V): Searching for "iec 60038 standard voltages pdf 103"
50 Hz Systems: The common standard is 230/400 V (single-phase/three-phase).
60 Hz Systems: Common values include 120/208 V and 120/240 V.
Industrial applications often use higher LV levels like 400/690 V. Medium-Voltage (MV) Systems (1 kV to 35 kV):
Standard values include 3.3 kV, 6.6 kV, 11 kV, 22 kV, and 33 kV. High-Voltage (HV) and Ultra-High Voltage (UHV): Covers transmission grids from 35 kV up to 1,100 kV. Critical Technical Specifications IEC 60038 Standard Voltage Classifications | PDF - Scribd

Most people think voltages are fixed. They are not. IEC 60038 acknowledges that the world runs on conflicting standards and gives a framework to manage the chaos.
