Figure 231: Connections of the SESRSYN (25) function block in a breaker-and-a-
half arrangement with internal voltage selection for the line 2 IED
The example shows the use of the SESRSYN function for the Tie
Circuit breaker in both Line IEDs. This depends on the arrangement of
Auto-reclose and manual closing and might often not be required.
The connections are similar in both IEDs, apart from the live voltages and bus
voltages, which are crossed. The line two IED in a breaker-and-a-half arrangement
handles voltage selection for busbar2 CB and for the tie CB. The IED requires two
