With the BOP, the signal transmitted is a trip block signal. When the reverse looking DEFR
operates, the logic level of the transmit signal CS becomes 1 and a trip block signal is transmitted.
When the trip block signal is received, R1-CR-DEF becomes 1.
When the forward looking DEFF operates, it executes tripping on condition that no trip blocking
signal should be received.
The delayed pick-up timer TCHD is provided to allow for the transmission delay of the trip block
signal from the remote terminal. Therefore, the time is set depending on the channel delay time.
TCHD setting = maximum signal transmission delay time(*) + 5ms
(*) includes delay time of binary output and binary input for the blocking signal.
The DEFR is also used for the current reversal logic (for current reversal, see Section 2.4.3.6).
When operation of the DEFR and non-operation of the DEFF last for 20 ms or more, even if the
DEFF operates or the DEFR is reset later, tripping of the local terminal is blocked for the TREBK
setting time and transmission of the trip block signal continues for the TSBCT setting time.
When the signaling channel of DEF BOP is separated from that of distance command protection,
the signal S-DEFBOP2 is used for CS and assigned to a user configurable binary output relay (see
Section 3.2.2.).

(*) Current values shown in the parentheses are in the case of 1 A rating. Other current values are in
the case of 5 A rating.
When the DEFF at the remote end operates, the local DEFR must always operate for reverse faults.
The setting levels of the residual current and residual voltage for the DEFR must be lower than that
for the DEFF.
The following setting elements are used in common with the distance protection or its setting is
interlinked with other elements listed above. So no setting operation is required here.
