•
OPEN BREAKER KEYING RST DELAY
: Delays the reset of open breaker keying to override disagreement between
main and auxiliary contacts of the breaker or any other operating conditions.
•
WEAK-INFEED KEYING
: This setting assigns a sensitive phase-current element for weak-infeed keying control. It
should be normally picked up with a minimum line load current. An instantaneous overcurrent element or a group of
overcurrent elements are suitable for this purpose.
•
WEAK-INFEED SUPV
: This setting selects a weak-infeed supervising element from FlexLogic operands. An under-
voltage element, auxiliary contacts of breakers indicating close position, or other elements can be useful for no-current
supervision.
•
WEAK-INFEED PICKUP DELAY
: This setting delays operation of weak-infeed keying during some transient condi-
tions (such as breaker reclosure, etc.).
•
WEAK-INFEED RESET DELAY
: The weak-infeed keying function incorporates a default 35 ms reset delay to assure
reset coordination with the FDH trip-level fault detector at the remote terminal during fault clearing. The default reset
time can be changed according to local conditions.
