Industrial plants, large commercial complexes, and municipal distribution networks. 3. High Voltage (HV) and Extra-High Voltage (EHV) Systems
IEC 60038 applies to AC transmission, distribution, and utilization systems (50/60 Hz) above 100 V, DC and AC traction systems, and various low-voltage equipment. Key classifications include: iTeh Standards Low Voltage (100–1000 V AC): Focuses on harmonizing systems toward the 230/400 V standard
One of the most significant achievements of IEC 60038 was the harmonization of European low-voltage systems. Previously, the UK used 240/415 V while continental Europe used 220/380 V. IEC 60038 successfully shifted these grids toward a unified nominal voltage of 230 V single-phase and 400 V three-phase . Common values include 3
IEC 60038, titled "IEC Standard Voltages," defines the standard voltage values used as reference points for electrical equipment design and power system planning. Without these unified values, manufacturers would have to build unique appliances, transformers, and motors for every single city or country, driving up costs and stalling industrial progress. The standard applies to:
Accessing the official documentation is essential for several engineering workflows:
Understanding IEC 60038 Standard Voltages The International Electrotechnical Commission (IEC) publishes consensus-based standards to harmonize electrical technologies worldwide. Among these, stands as one of the most foundational documents in power engineering. It defines a standardized list of nominal voltages for public and industrial supply systems, traction systems, and electrical equipment.
