The most widely recognized three-phase, four-wire system listed in IEC 60038 is the system. This system evolved from the harmonization of Europe's older 220V/380V and 240V/415V systems.
The IEC 60038 standard ensures that electrical power systems operate within a defined voltage range, which helps to: iec 60038 standard voltages pdf 103
: For LV systems, the supply voltage should generally stay within $\pm$10% of the nominal value under normal conditions.
Do you need assistance calculating for a specific line length?
The standard distinguishes between system voltage (what the grid supplies) and equipment voltage (what a device is tested for). A 400V-rated motor must actually withstand 440V continuously per the standard.
: It ensures electrical appliances operate safely across different countries. Above 1kV, the standard doesn't pick favorites
Extra-High Voltage (EHV) grids form the core transmission lines of national grids. : 3. Understanding Voltage Tolerances

Up to 1,000 V. The most common standard nominal voltage for three-phase systems is for single-phase systems. Medium Voltage (MV):
Standardizing nominal DC voltages (such as 600 V, 750 V, 1,500 V, and 3,000 V) used in electric trains, subways, and light rail networks. If you share with third parties, their policies apply
: The standard split-phase system used primarily in North America.

The document summarizes standards for AC power systems from 100V to 35kV as defined by IEC 60038. It lists nominal voltages for 3-
(50 Hz and 60 Hz) with nominal voltages above 100 V. DC and AC traction systems , such as railways.
