Figure 110: 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 110. 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 110. The voltage selection parameter CBConfig is set
to Double bus.
