Figure 73: Connection of SESRSYN (25) function block in a single busbar
arrangement
Figure 73 illustrates connection principles. For the SESRSYN (25) function there is one
voltage transformer on each side of the circuit breaker. The voltage transformer circuit
connections are straightforward; no special voltage selection is necessary.
The voltage from busbar VT is connected to V3PB1 and the voltage from the line VT is
connected to V3PL1. The positions of the VT fuses shall also be connected as shown
above. The voltage selection parameter CBConfig is set to No voltage sel.
