Yes, 11 kV (11,000 volts) is considered high voltage. In electrical engineering and power distribution systems, voltage levels are generally classified into different categories: low voltage (LV), medium voltage (MV), high voltage (HV), and extra high voltage (EHV).
The classification can vary by country and standard, but typically:
- **Low Voltage (LV):** Up to 1,000 volts (1 kV)
- **Medium Voltage (MV):** 1 kV to 35 kV
- **High Voltage (HV):** 35 kV to 230 kV
- **Extra High Voltage (EHV):** 230 kV and above
Since 11 kV falls within the 1 kV to 35 kV range, it is considered **medium voltage**. However, in some contexts, especially in certain countries or industries, anything above 1 kV might be informally referred to as high voltage for practical purposes such as safety and insulation requirements.
In summary, while 11 kV is technically medium voltage by standard classifications, it is often referred to as high voltage in common usage, particularly when discussing electrical safety and transmission systems.
