Loop Restoration
118 S&C Instruction Sheet 766-530
Automatic Enable of Loop Restoration for Manual Lever Open (Normally
Open state)
When checked for a normally open IntelliRupter fault interrupter and after loop
restoration has reconfigured the feeder, a manual lever Open operation re-enables the
Loop Restoration mode. This operation returns the IntelliRupter fault interrupter to
the Ready state without a Wi-Fi or SCADA command. A manual lever Open operation
re-enables the Loop Restoration mode when the IntelliRupter fault interrupter is in
either the Open or Closed state.
Automatic Enable of Loop Restoration for Manual Lever Close (Normally
Closed state)
When checked for normally closed IntelliRupter fault interrupter and after loop
restoration has reconfigured the feeder, a manual lever Close operation re-enables the
Loop Restoration mode. This operation returns the IntelliRupter fault interrupter to
the Ready state without a Wi-Fi or SCADA command. A manual lever Close operation
re-enables the Loop Restoration mode when the IntelliRupter fault interrupter is in
either the Open or Closed state.
Automatic Enable of Loop Restoration for Hot Line Tag Removal
When unchecked, applying the Hot Line Tag mode for an IntelliRupter fault interrupter
with the Loop Restoration mode enabled and in the Ready state will result in the Loop
Restoration mode going to the Not Ready state and the Loop Restoration mode going
to the Disabled state.
When checked, applying the Hot Line Tag mode for an IntelliRupter fault interrupter
with the Loop Restoration mode enabled and in the Ready state will result in the
Loop Restoration mode going to the Not Ready state, but it will not disable the Loop
Restoration mode. When the Hot Line Tag mode is removed, all Ready conditions
are met, and the Loop Restoration mode was not disabled by a manual operation or a
command to disable the Loop Restoration mode, the Loop Restoration mode will go
back to the Ready state.
Time Delay Before First Test
This applies to the normally open configuration only. After loss of voltage on one side,
the IntelliRupter fault interrupter will wait this time period before executing the Close
test or a test using PulseClosing Technology as configured for Test 1. (Range: 0.0-600.0;
Step: 0.1 second; Default 45.0)
Maximum Time Allowed for Restoration
If the Loop Restoration mode is not complete when this timer expires, the Loop
Restoration mode is set to the Disabled state. Protection elements are still active,
except those designated Loops Only mode. The only exception is that an IntelliRupter
fault interrupter in the Closed state may enter the Loop Restoration mode Ready
state if all other conditions are met. An IntelliRupter fault interrupter in the Open state
in the middle of a test sequence will not complete the sequence if the timer expires.
Therefore, the Maximum Time Allowed for Restoration setpoint must be longer than
the combined times of the slowest initial trip response and the Test Sequence Times
setting configured in the general profile enabled for the Loop Restoration mode. The
choices are 0 (which sets the value to None and indicates no time limit) or a specific time
setting. (Range: 5-6,000; Step: 0.1 second; Default: 300.0)
