This one-line diagram shows an electrical distribution system with multiple components connected by buses at different voltage levels. It includes 3 transmission lines, 2 main transformers, 8 distribution transformers, numerous circuit breakers, switches and fuses connecting 44 buses at both 138kV and 34.5kV levels. The diagram provides a visual representation of how power flows through the system from high voltage transmission to lower voltage distribution.
