Distribution lines are energized at voltages between what ranges?

• A. 1kv and 2kv
• B. 2kv and 34.5kv
• C. 34.5kv and 69kv
• D. 100kv and 230kv

Answer: (B)

Distribution lines typically operate at voltages that range from 2 kilovolts (kV) to 34.5 kV. This range is characteristic of the medium-voltage distribution networks used to deliver electricity to local areas from substations. The voltage levels within this range are suitable for distributing power over moderate distances while maintaining efficiency and safety for end-users. Voltages below 2 kV are usually found in low-voltage systems within residential or small commercial applications, while voltages above 34.5 kV generally fall into the high-voltage transmission category, which serves to transport electricity over longer distances with minimal losses. Thus, the specified range from 2 kV to 34.5 kV accurately reflects the typical operational voltages for distribution lines.
