4.1.5

P/F Shots sub-menu

This menu allows the Phase fault trip/reclose sequence to be parameterized:-
The first protection Trip in the P/F sequence can be set to either Inst or Delayed.
79 P/F Prot'n Trip1
Sets the first Reclose Delay (Dead time) in the P/F sequence.
79 P/F Deadtime 1
The second protection Trip in the P/F sequence can be set to either Inst or Delayed.
79 P/F Prot'n Trip2
Sets the second Reclose Delay (Dead time) in the P/F sequence.
79 P/F Deadtime 2
The third protection Trip in the P/F sequence can be set to either Inst or Delayed.
79 P/F Prot'n Trip3
Sets the third Reclose Delay (Dead time) in the P/F sequence.
79 P/F Deadtime 3
The fourth protection Trip in the P/F sequence can be set to either Inst or Delayed.
79 P/F Prot'n Trip 4
Sets the fourth Reclose Delay (Dead time) in the P/F sequence.
79 P/F Deadtime 4
The fifth and last protection Trip in the P/F sequence can be set to either Inst or
79 P/F Prot'n Trip5
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.
4.1.6

E/F Shots sub-menu

This menu allows the Earth Fault trip/reclose sequence to be parameterized:-
As above but E/F settings.
4.1.7

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
4.1.8

Extern Shots sub-menu

This menu allows the External Protection auto-reclose sequence to be parameterized:-
Not Blocked/Blocked - Blocked raises an output which can be mapped to a Binary
79 P/F Prot'n Trip1
output to Block an External Protection's Trip Output.
Sets the first Reclose Delay ( Deadtime) for the External sequence.
79 P/F Deadtime 1
Not Blocked/Blocked - Blocked raises an output which can be mapped to a Binary
79 P/F Prot'n Trip2
Output to Block an External Protection's second Trip output.
Sets the second Reclose Delay ( Deadtime) in the External sequence.
79 P/F Deadtime 2
Not Blocked/Blocked - Blocked raises an output which can be mapped to a Binary
79 P/F Prot'n Trip3
output to Block an External Protection's third Trip Output.
Sets the third Reclose Delay (Deadtime) in the External sequence.
79 P/F Deadtime 3
Not Blocked/Blocked - Blocked raises an output which can be mapped to a Binary
79 P/F Prot'n Trip4
output to Block an External Protection's fourth Trip Output.
Sets the fourth Reclose Delay (Deadtime) in the External sequence.
79 P/F Deadtime 4
Not Blocked/Blocked - Blocked raises an output which can be mapped to a Binary
79 P/F Prot'n Trip5
output to Block an External Protection's fifth Trip Output.
