Distance Scheme setting
Program mode Standard or open scheme
Standard Modes:
∗ Basic + Z1X,
∗ POP Z1,
∗ POP Z2,
∗ PUP Z2,
∗ PUP Forward,
∗ BOP Z1,
∗ BOP Z2.
POP = Permissive Overreach Protection
PUP = Permissive Underreach Protection
BOP = Blocking Overreach Protection
Fault type:
∗ Phase to Ground,
∗ Phase to Phase,
∗ Both enabled.
Trip Mode:
∗ Force 3 Pole,
∗ 1 Pole Z1 and Carrier Received (CR),
∗ POP Z1 Z2 and CR.
Signal sent from a zone to the relays setting
(open scheme):
∗ CsZ1 (Carrier sent by Z1),
∗ CsZ2,
∗ CsZ4.
Aided scheme on Carrier receipt “Dist CR”
(open scheme):
∗ None,
∗ PermZ1: Permissive Z1 (Z1 can trip without
waiting the end of tZ1 timout),
∗ PermZ2,
∗ PermFwd (forward),
∗ Blocking Z1 (BlkZ1) (Z1 can only trip if a
Carrier is not received),
∗ BlkZ2.
Additional time-delay for PUP Z2, PUP FWD,
POP Z1 and POP Z2 schemes:
0 to 1 s (stem 2 ms)
tReversal Guard: 0 to 0.15 s (step 2 ms)
Unblocking schemes (with permissive
schemes):
∗ None,
∗ Loss of Guard mode,
∗ Loss of Carrier mode.
