 		 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
22.10 Envelope and low frequency

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
