The main connection is a single busbar
The single bus is the simplest substation topology: every incoming and outgoing circuit connects to one common bus through its own circuit breaker and isolators. Variants include a sectionalized single bus, where one or more bus couplers divide the bus into segments to limit the extent of outages. Independently of the number of feeders supplied according to the topology of the system, no supply reserve exists for the outage of the transformer or of the busbar. The transformer can be loaded up to 100. Single Bus-bar System: The single bus-bar system has the simplest design and is used for power stations. It can be solid, hollow, or flexible, and comes in various shapes. Essentially, it's an electrical.
