Using TripSaver

II Service Center Configuration Software Version 1.8
Cold Wakeup NR
The
Cold Wakeup NR
setting is configured when a separate curve is desired in response
to a cold wakeup of the TripSaver II recloser. See Figure 91. In most cases, this is a slower
curve. This setting will be used by the TripSaver II recloser when the MODE-SELECTOR
lever is in the
Down
position or when the recloser is in the
R-NR
mode. After 10 cycles,
if a current above the
Current, A
setting is not detected, the Cold Wakeup NR curve
will revert to the Standard NR curve.
The
Cold Wakeup TCC
curve will not be used in a “post-fault” situation, where the
load is being picked up after the TripSaver II recloser has previously dropped open. In
those cases, the Post Fault Wakeup NR curve will be used. See Figure 90 on page 60.
If a
Cold Wakeup NR
setting is not required, set the TCC curve to the same settings
as the
Standard NR
setting.
