Is it true that electricity is usually generated in power plants at distribution voltage?

Is it true that electricity is usually generated in power plants at distribution voltage?

• A. True
• B. False
• C. Depends on the plant
• D. Only in small plants

Answer: (B)

Electricity from a central power plant is not produced at distribution voltage. The generator itself creates electricity at its own generator voltage, typically a few kilovolts. That voltage is then boosted by a transformer to a high transmission voltage for long-distance transport, where the voltage is tens or hundreds of kilovolts. Along the way, substations progressively step the voltage down through distribution transformers, eventually delivering safe, usable voltages to homes and businesses. The high-voltage transmission is used to minimize current and reduce losses over long distances, while distribution voltage is what we use at the end of the line. So the statement is false.
