Figure 304: Connection of the SESRSYN 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 304. The voltage from the busbar 1 VT is connected to V3PB1
and the voltage from busbar 2 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
304. The voltage selection parameter CBConfig is set to Double bus.
