Synchronization in a Breaker-and-a-Half Arrangement
Each synchronization function requires 2 comparison voltages. For the circuit breaker QA2 located in the
middle, there are 2 options for each side (V
sync1
and V
sync2
). The selection of synchronization voltages for each
side depends on the position of the circuit breaker and the disconnectors.
For circuit breakers QA1 and QA3, the busbar voltage (V
sync1
) is available for one side, and 3 voltages (V
sync2
)
are available for the other side.
Connecting Measuring Points to Circuit-Breaker Function Group
The following figure shows the connection of the Circuit-breaker function group with several measuring
points in DIGSI. The ID of each measuring point appears in parentheses after the name.
