The connections are similar in all SESRSYN functions, apart from the breaker position
indications. The physical analog connections of voltages and the connection to the IED
and SESRSYN (25) function blocks must be carefully checked in PCM600. In all
SESRSYN functions the connections and configurations must abide by the following
rules: Normally apparatus position is connected with contacts showing both open (b-
type) and closed positions (a-type).

A1_QA1:
• BUS1_OP/CL = Position of TIE_QA1 breaker and belonging disconnectors
• BUS2_OP/CL = Position of WA2_QA1 breaker and belonging disconnectors
• LINE1_OP/CL = Position of LINE1_QB9 disconnector
• LINE2_OP/CL = Position of LINE2_QB9 disconnector
• VB1OK/FF = Supervision of WA1_MCB fuse
• VB2OK/FF = Supervision of WA2_MCB fuse
• VL1OK/FF = Supervision of LINE1_MCB fuse
• VL2OK/FF = Supervision of LINE2_MCB fuse
• Setting CBConfig = 1 1/2 bus CB
TIE_QA1:
• BUS1_OP/CL = Position of WA1_QA1 breaker and belonging disconnectors
• BUS2_OP/CL = Position of WA2_QA1 breaker and belonging disconnectors
• LINE1_OP/CL = Position of LINE1_QB9 disconnector
• LINE2_OP/CL = Position of LINE2_QB9 disconnector
• VB1OK/FF = Supervision of WA1_MCB fuse
• VB2OK/FF = Supervision of WA2_MCB fuse
• VL1OK/FF = Supervision of LINE1_MCB fuse
• VL2OK/FF = Supervision of LINE2_MCB fuse
• Setting CBConfig = Tie CB
WA2_QA1:
• BUS1_OP/CL = Position of WA1_QA1 breaker and belonging disconnectors
• BUS2_OP/CL = Position of TIE_QA1 breaker and belonging disconnectors
• LINE1_OP/CL = Position of LINE1_QB9 disconnector
• LINE2_OP/CL = Position of LINE2_QB9 disconnector
• VB1OK/FF = Supervision of WA1_MCB fuse
• VB2OK/FF = Supervision of WA2_MCB fuse
• VL1OK/FF = Supervision of LINE1_MCB fuse
• VL2OK/FF = Supervision of LINE2_MCB fuse
• Setting CBConfig = 1 1/2 bus alt. CB
If only two SESRSYN functions are provided in the same IED, the connections and
settings are according to the SESRSYN functions for WA1_QA1 and TIE_QA1.
