In typical grid planning, 230 kV is most associated with which layer of the system?

• A. Distribution Systems
• B. Industrial Customer Systems
• C. Transmission Systems
• D. Generation Systems

Answer: (C)

230 kV is a high-voltage level used for transferring bulk power over long distances, which places it in the transmission layer of the grid. In typical grid planning, electricity is generated at plants, then stepped up to transmission voltages for efficient long-distance travel, and later stepped down through substation equipment to subtransmission and distribution voltages for delivery to customers. Distribution operates at much lower voltages, and generation is about producing power, not the long-distance transfer. So 230 kV lines are characteristic of the transmission systems.
