Standard IEC 38 defines voltage ratings as follows:
- Low voltage (LV)
For a phase-to-phase voltage between 100 V and 1000 V. The standard ratings
are: 400 V - 690 V - 1000 V (at 50 Hz)
- Medium voltage (MV)
For a phase-to-phase voltage between 1000 V and 35 kV. The standard ratings
are: 3.3 kV - 6.6 kV - 11 kV - 22 kV - 33 kV
- High voltage (HV)
For a phase-to-phase voltage between 35 kV and 230 kV. The standard ratings
are: 45 kV - 66 kV - 110 kV - 132 kV - 150 kV - 220 kV.[/LEFT]
