POP tripping
(Integral digital communication)
Set the scheme switch [SCHEME] to "POP", [WKIT] and [ECHO] to "off".
Set the [T.TEST] to “ON”.
Apply a zone 1 fault. Check that instantaneous single-phase or three-phase tripping is performed
depending on the fault types and setting of autoreclose mode selection switch [ARC-M].
Apply a reverse zone fault, and check that the POP tripping does not occur.
Check that the indications and recordings are correct.
(External communication)
Set the scheme switch [SCHEME] to "POP", [WKIT] and [ECHO] to "off".
Energize the binary input (EXT-CAR-R1) to simulate a trip permission signal reception and apply
a zone 2 fault. Check that instantaneous single-phase or three-phase tripping is performed
depending on the fault types and setting of autoreclose mode selection switch [ARC-M].
Set [WKIT] and [ECHO] to "On" and apply a weak-infeed fault. Check that instantaneous tripping
is performed.
De-energize the binary input and apply a zone 2 fault. Check that POP tripping does not occur.
Apply a zone 2 fault, and check that binary output relay (EXT-CAR-S) operates.
Set the scheme switch [ECHO] to "On".
De-energize binary inputs (CB_CONT-A, -B and -C signals are assigned.) to simulate the breaker
being open. Check that binary output relay (EXT-CAR-S) operates when the binary input
(EXT-CAR-R1) is energized.
Apply a reverse zone fault while the binary inputs (CB_CONT-A, -B and -C) are energized, and
check that the binary output relay (EXT-CAR-S) does not operate when the binary input
(EXT-CAR-R1) is energized.
Check that the indications and recordings are correct.
UOP tripping
(Integral digital communication)
Set the scheme switch [SCHEME] to "UOP", [WKIT] and [ECHO] to "Off".
Set the [T.TEST] to “ON”.
Apply a zone 1 fault. Check that instantaneous single-phase or three-phase tripping is performed
depending on the fault types and setting of autoreclose mode selection switch [ARC-M].
Apply a reverse zone fault, and check that the UOP tripping does not occur.
(External communication)
Set the scheme switch [SCHEME] to "UOP", [WKIT] and [ECHO] to "Off".
De-energize the binary input (EXT-CAR-R1) to simulate interruption of a trip block signal
reception and apply a zone 2 fault. Check that instantaneous single-phase or three-phase tripping
is performed depending on the fault types and setting of autoreclose mode selection switch
[ARC-M].
Set [WKIT] and [ECHO] to "On" and apply a weak-infeed fault. Check that instantaneous tripping
is performed.
