2.4.15 Tripping Output Signals
The single-phase tripping signals drive the high-speed tripping output relays according to the
tripping logic in Figure 2.4.15.1.
Two sets of output relays are provided for each phase and each relay has one normally open
contact.
The tripping output relays reset 60ms(*) after the S-TRIP or M-TRIP signal disappears by clearing
the fault. The tripping circuit must be opened with a circuit breaker auxiliary contact prior to the
trip relay resetting in order to prevent the tripping relay from directly interrupting the circuit
breaker tripping coil current.
(*) Reset time is adjustable by PLC function. Default setting is 60ms.
In the following cases, per-phase-based tripping is converted to three-phase tripping.
•
When autoreclose is prohibited by a binary input signal (ARC_BLOCK = 1)
•
When the tripping mode selection switch [TPMODE] is set to "3PH"
(This applies to the GRZ100 model 100s which does not have autoreclose.)
•
When the autoreclose mode selection switch [ARC-M] is set to "EXT3P"
•
PLC command “3P_TRIP” is established.
For the following trips, the logic level of M-TRIPA becomes 1, and single-phase tripping is then
forced to convert to three-phase tripping. For details of M-TRIPA, see Figure 2.6.2.1.
•
Tripping while reclaim is in progress.
•
Tripping when the reclose mode selection switch [ARC-M] is set to "Disabled" or "TPAR"
The signals TRIP-A, TRIP-B and TRIP-C are used to start the autoreclose.
The signal TRIP is used to initiate the breaker failure protection.
