Phase selection
GUID-6C316E54-8CEF-48C6-8FBB-DCE65DBD5956 v2
ModePhSelKI: Set this to Off.
KI: Set this to 1.2.
I01: This setting is used to detect high short circuit current during blocking time
tI01 when starting element impedance loop has picked up. Set at 400% IB.
ModeI0StRel: Set this to L1E and L2E
I0MinPhSel: Set this to 4% IB.
tI0: This is delay time for residual overcurrent start. Residual overcurrent start is
delayed by settable time delay tI0. Set this to 0.2s.
tI01: This is blocking time of distance measuring for transient earth fault. Set this
to 0.1s.

ModePhPr
ef: Set this to L1 befor
e L2.
OpModet1L2: Set this to On.
t1L2: Set this to 1.0s.
OpModet2L2: Set this to On.
t2L2: Set this to 2.0s.
OpModet3L2: Set this to On.
t3L2: Set this to 3.0s.
U0Min: This is used to check minimum residual voltage if start signal falls back.
Set this to 50% UB.
tVL2: This is used to extend the time for phase L2 to check the voltage shift. To
time t0L2 to t6L2 is a settable time tVL2 (operation time extension L2) added. Set
this to 0.5s.
OpModetGL2: Set this to On.
tGL2: This is an additional time delay to trip L2 in compensated earthing. If the
start signal continues to be active, trip is given after expiration tPEZx plus tGL2.
Set this to 0.6s.
dUOverdt: Set this to 100V/s.
