P/F Shots Sub-Menu
This menu allows the Phase fault trip/reclose sequence to be parameterized:-
79 P/F Prot’n Trip1
The first protection Trip in the P/F sequence can be set to either
Inst
or
Delayed.
79 P/F Deadtime 1
Sets the first Reclose Delay (Dead time) in the P/F sequence.
79 P/F Prot’n Trip2
The second protection Trip in the P/F sequence can be set to either
Inst
or
Delayed.
79 P/F Deadtime 2
Sets the second Reclose Delay (Dead time) in the P/F sequence.
79 P/F Prot’n Trip3
The third protection Trip in the P/F sequence can be set to either
Inst
or
Delayed.
79 P/F Deadtime 3
Sets the third Reclose Delay (Dead time) in the P/F sequence.
79 P/F Prot’n Trip 4
The fourth protection Trip in the P/F sequence can be set to either
Inst
or
Delayed.
79 P/F Deadtime 4
Sets the fourth Reclose Delay (Dead time) in the P/F sequence.
79 P/F Prot’n Trip5
The fifth and last protection Trip in the P/F sequence can be set to either
Inst
or
Delayed
.
79 P/F HighSet Trips to Lockout
Sets the number of allowed HighSet trips. The relay will go to Lockout on the
last HighSet Trip. This function can be used to limit the duration and number of high
current trips that the Circuit Breaker is required to perform, if the fault is permanent
and close to the Circuit Breaker then there is no point in forcing a number of Delayed
Trips before the Relay goes to Lockout – that sequence will be truncated.
79 P/F Delayed Trips to Lockout
Sets the number of allowed Delayed trips, Relay will go to Lockout on the last
Delayed Trip. This function limits the number of Delayed trips that the Relay can
perform when the Instantaneous protection Elements are externally inhibited for
system operating reasons - sequences are truncated.

E/F Shots Sub-Menu
This menu allows the Earth Fault trip/reclose sequence to be parameterized:-
As above but E/F settings.
4.6
SEF Shots Sub-Menu
This menu allows the Sensitive Earth trip/reclose sequence to be parameterized:-
As above but SEF Settings, Note: - SEF does not have HighSets
