Figure 17. System Configuration One-Line Diagrams
The diagrams in Figure 17 show all breakers in the open position and all buses in a dead/unstable state.
Breaker and bus states in the diagram change in real time to reflect the actual breaker and bus status.
When a breaker is open, the line between the contacts is vertical and when closed the line is horizontal. A
stable bus is indicated by a filled rectangle and a bus in any state other than stable is indicated by an
unfilled rectangle. See Figure 18 for the different breaker and bus states.
