another recloser downstream
22.5Auto-re-closerRelay 79 (sequence 1,2,3,4)
Operating Sequence
Reclose times are individually selectable. The operating sequence is defined by:

setting is available for Sensitive Earth Fault and Negative Phase Sequence.

Threshold voltage range: 2 - 15kV
Voltage resolution: 1V
Time range: 0.1 - 100 sec
Time resolution: 0.1 sec
22.8Live load blocking

are live.
Live Load Threshold Voltage range: 2 - 15kV
22.9Dead lockout
Dead lockout prevents a reclose unless one or more of the source side or load side
terminals are live. If all terminals are dead, then the controller goes to lockout
22.10Envelope and low frequency

over frequency trip threshold values. Frequency tripping range: 45 - 65 Hz

22.13DistanceRelay 21
22.14Directional blocking
Directional protection
67 relay PGQ/67N
a protection feature that restricts tripping on faults to a
designated side of the re-closer. It prevents nuisance tripping if network
conditions are causing "false" earth faults. In radial systems, Directional Blocking
prevents nuisance tripping by blocking faults in the source direction and only responding to faults in the load direction.
Distinct protection for faults in the forward and reverse direction. A forward fault may
use a different time-current curve and settings to a reverse fault (i.e. these are
individually selectable). Both the forward protection and reverse protection are
operating at the same time. This is an additional protection feature
