SPAR logic – settings (TSPAR1, TRR1)

The SPAR logic for CB#1 and CB#2 is illustrated in Figure 2.34-18. The 'ARC1_SPAR' signal

is generated when the SPAR condition is appeared in the Condition logic; the SPAR logic has

the dead timer [TSPAR1] provided to delay issuing a reclose command, which turns into 'ARC1

SHOT1' signal later. The user should set the [TRR1] to have the coordination with the

[TSPAR1]; the final trip will occur when 'ARC1-S1 TRR' signal is present. The SPAR logic for

CB#2 is similar to the one for CB#1.
