Figure 99:
Connection of SESRSYN function block in a single breaker, double
busbar arrangement with external voltage selection
In this type of arrangement no internal voltage selection is required. The voltage
selection is made by external relays typically connected according to figure
Suitable voltage and VT fuse failure supervision from the two busbars are selected
based on the position of the busbar disconnectors. This means that the connections
to the function block will be the same as for the single busbar arrangement. The
voltage selection parameter
CBConfig
is set to
No voltage sel
