Single-line diagram of AC transmission and distribution system· Figure 1 – Single-line diagram of transmission and distribution network. Central station where power is generated by 3-phase alternators. In Figure 1 C.S. represents the central station where power is generated by 3-phase alternators at 6.6kV or 11kV or 13.2kV or even 32 kV. The voltage is then stepped up by suitable 3-phase transformers for transmission purposes.
