: Standard values include 750 V, 1,500 V, and 3,000 V.
: It provides a specific list of values that should be used for electrical supply systems, helping to unify grids worldwide. iec 60038 standard voltages pdf 103
: Includes a variety of North American and international standards, such as 120/208 V , 120/240 V (split-phase), and 277/480 V . High Power Industrial : Uses 400/690 V and up to 1,000 V. 2. Traction Systems (AC and DC) : Standard values include 750 V, 1,500 V, and 3,000 V
The standard, titled " IEC Standard Voltages ", is the definitive international reference for nominal electricity supply voltages. Developed by the International Electrotechnical Commission (IEC) , it establishes preferential values for both AC and DC systems to ensure global interoperability and safety. Core Objectives of IEC 60038 The standard serves two primary functions: High Power Industrial : Uses 400/690 V and up to 1,000 V
