Extern Shots Sub-Menu
This menu allows the External Protection auto-reclose sequence to be parameterized:-
79 P/F Prot’n Trip1
Not Blocked/Blocked
- Blocked raises an output which can be mapped to a Binary
output to Block an External Protection’s Trip Output.
79 P/F Deadtime 1
Sets the first Reclose Delay (Deadtime) for the External sequence.
79 P/F Prot’n Trip2
Not Blocked/Blocked
- Blocked raises an output which can be mapped to a Binary
Output to Block an External Protection’s second Trip output.
79 P/F Deadtime 2
Sets the second Reclose Delay (Deadtime) in the External sequence.
79 P/F Prot’n Trip3
Not Blocked/Blocked -
Blocked raises an output which can be mapped to a Binary
output to Block an External Protection’s third Trip Output.
79 P/F Deadtime 3
Sets the third Reclose Delay (Deadtime) in the External sequence.
79 P/F Prot’n Trip4
Not Blocked/Blocked
- Blocked raises an output which can be mapped to a Binary
output to Block an External Protection’s fourth Trip Output.
79 P/F Deadtime 4
Sets the fourth Reclose Delay (Deadtime) in the External sequence.
79 P/F Prot’n Trip5
Not Blocked/Blocked
- Blocked raises an output which can be mapped to a Binary
output to Block an External Protection’s fifth Trip Output.
79 P/F Extern Trips to Lockout
- Sets the number of allowed External protection’ trips, Relay will go to Lockout
on the last Trip.
These settings allow the user to set-up a separate AutoReclose sequence for external protection(s) having a
different sequence to P/F, E/F or SEF protections. The
‘ Blocked ‘
setting allows the Autoreclose sequence to
raise an output at any point in the sequence to Block further Trips by the External Protection thus allowing the
Overcurrent P/F or Earth Fault or SEF elements to apply Overcurrent Grading to clear the fault.
Other Protection Elements in the Relay can also be the cause of trips and it may be that AutoReclose is required;
the External AutoReclose sequence can be applied for this purpose. By setting-up internal Quick Logic
equation(s) the user can define and set what should occur when any one of these other elements operates.
