to
BRK 1 FLSHOVR SPV C
: These settings specify FlexLogic operands (per breaker pole)
that supervise the operation of the element per phase. Supervision can be provided by operation of other protection
elements, breaker failure, and close and trip commands. A six-cycle time delay applies after the selected FlexLogic
operand resets.
•
BRK FLSHOVR PKP DELAY
: This setting specifies the time delay to operate after a pickup condition is detected.

CT TROUBLE ZONE 1(2)
This element uses the differential current calculated in accordance with the bus configuration programmed under Bus Zone
1. Operation of this element is therefore completely dependent on the dynamic bus replica, which must be defined first. The
bus differential zones are defined using the path

BUS
. The CT Trouble element 1 detects
CT problems in any of the circuits actually connected to the differential zone defined as Bus Zone 1.
The
CT TROUBLE ZONE 1 PICKUP
setting specifies the differential current level that defines an abnormal bus state. If the dif-
ferential current in a given phase remains above this level for the time interval defined by the
CT TROUBLE ZONE 1 DELAY
setting, CT Trouble is declared for the given phase by setting the appropriate FlexLogic output operand.
