Figure 5–129: ILLUSTRATION OF THE INCIPIENT FAULT DETECTOR ALGORITHM
The following settings are available for each incipient cable fault detector.
•
INCIPIENT FAULT 1 FUNCTION
: This setting enable and disables operation of the incipient fault detection element.
•
INCIPNT FLT 1 BLOCK
: This setting is used to block operation of the incipient cable fault detector element. Assertion
of the FlexLogic™ operand assigned to this setting block operation.
•
INCIPIENT FAULT 1 SOURCE
: This setting selects a current source for the incipient cable fault detector element. This
source must be assigned a valid CT bank.
•
INCIPIENT FAULT 1 PICKUP
: This setting specifies pickup level of the overcurrent detector in per-unit values of the
CT nominal current.
•
INCIPNT FLT 1 MODE
: There are two modes of operation available for the incipient cable fault detector element. In
the “Number of counts” mode, a trip will be initiated only after the selected number of faults is detected. In the “Counts
per window” mode, a trip will be initiated only after the selected number of faults is detected within the time specified by
the
INCIPNT FLT 1 DETECT WINDOW
setting.
•
INCIPIENT FLT 1 TRIP COUNTS NUMBER
: This setting selects the number of faults required to initiate a trip.
•
INCIPNT FLT 1 DETECT WINDOW
: This setting specifies a time window for “Counts per window” mode of operation.
•
INCIPIENT FAULT 1 RESET DELAY
: This setting specifies a reset time for the output after the trip is initiated.
