Voltage Levels in India (LV / MV / HV)
Indian power systems use a set of standard voltage levels across distribution and transmission.
| Level | Voltage | Use |
|---|---|---|
| LV | 230 V / 415 V | Consumer / distribution |
| MV | 11 kV / 33 kV | Primary distribution |
| HV | 66 kV / 132 kV | Sub-transmission |
| EHV | 220 kV / 400 kV | Transmission |
| UHV | 765 kV | Bulk transmission |
Structures and switchgear are rated to the relevant voltage class and clearances.
