Figure 134: Connection of the SESRSYN (25) function block in a single breaker,
double busbar arrangement with internal voltage selection.
When internal voltage selection is needed, the voltage transformer circuit connections are
made according to figure 134. The voltage from busbar1 VT is connected to V3PB1 and
the voltage from busbar2 VT is connected to V3PB2. The voltage from the line VT is
connected to V3PL1. The positions of the disconnectors and VT fuses shall be connected
as shown in figure 134. The voltage selection parameter CBConfig is set to Double bus.
