You can find more information on IEC 60038 and download the standard from the IEC website.
It applies to AC transmission and distribution at 50 Hz and 60 Hz frequencies for voltages above 100 V, as well as traction systems and low-voltage equipment (below 120 V AC or 750 V DC). Voltage Band Categories: AC systems from 100 V to 1,000 V (Low Voltage). AC and DC traction systems (e.g., railways). AC systems from 1 kV up to 35 kV (Medium Voltage). AC systems from 35 kV to 230 kV (High Voltage). AC systems exceeding 245 kV (Ultra-High Voltage). Horizontal Status: Classified under IEC Guide 108
Utilities use these values to ensure new grid infrastructure is stable and interoperable. Manufacturing:
The standard defines key terms like nominal, supply, and utilization voltage to ensure equipment compatibility.
