Figure 2.15.2.9 shows the energizing control scheme of the two circuit breakers in the
three-phase autoreclose. OVB and UVB are the overvoltage and undervoltage detectors of
busbar voltage VB in Figure 2.15.2.7. OVL1 and UVL1 are likewise the overvoltage and
undervoltage detectors of line voltage VL1.
OVL2 and UVL2 are likewise the overvoltage and undervoltage detectors of line voltage VL2.
VL2 in the center breaker is equivalent to the busbar voltage VB in the busbar breaker.
SYN1 and SYN2 are the synchronism check elements to check synchronization between the two
sides of the busbar and center breakers, respectively. SYN-OP is a voltage and synchronism
check output.
