: The primary standard is 230/400 V . This was harmonized from older 220/380 V and 240/415 V systems, a transition completed in most of Europe by 2003.
This is the most common range for residential and commercial use. iec 60038 standard voltages pdf 103
The standard organizes voltage levels into several "bands" or categories to address different industrial and residential needs: : The primary standard is 230/400 V
: Standardized at 15,000 V (16.7 Hz) or 25,000 V (50/60 Hz). 3. Medium and High Voltage (MV/HV) Systems IEC 60038:2009 - iTeh Standards 000 V (16.7 Hz) or 25
: It defines the maximum, nominal, and minimum reference values that equipment and system manufacturers must use during the design and testing phases. Standard Voltage Classifications
