11 kV (kilovolt) refers to an electrical voltage level of 11,000 volts. It is a commonly used voltage level in electrical distribution systems, particularly for medium-voltage networks.
In simple terms:
- Voltage is the force that pushes electrical current through a circuit.
- 11 kV means the potential difference (or electrical pressure) between two points is 11,000 volts.
This voltage is typically used for power transmission in substations to distribute electricity from power plants to smaller transformers, which then reduce the voltage to lower levels (like 230V or 120V) for homes and businesses.
For example, in an industrial or residential area, the electricity you use could have been delivered through power lines that carry this 11 kV voltage, and then it would be stepped down to a safer and more usable voltage (like 220V) for everyday devices.
