Power transmission refers to the process of transferring electrical energy from one place to another, typically from power plants to homes, businesses, or factories, using power lines or cables. The goal is to transport electricity over long distances with minimal loss of energy.
Here’s how it works in simple terms:
1. **Power Generation**: Electricity is generated at a power plant (like coal, gas, nuclear, or renewable energy sources).
2. **Step-Up Transformation**: The voltage of the electricity is increased using a transformer. This is done because high voltage helps in reducing the loss of energy as heat during transmission.
3. **Transmission**: The high-voltage electricity is sent through power lines or cables across long distances, sometimes even hundreds of kilometers.
4. **Step-Down Transformation**: Once it reaches the destination area, the voltage is reduced to a safer level using another transformer, so it can be used by homes and industries.
5. **Power Distribution**: Finally, the electricity is distributed to homes and businesses via local power lines.
In essence, power transmission involves carrying electricity efficiently over long distances to ensure that it can be used where it's needed.
