Informational and Settings Screens
Pure Sectionalizing mode occurs where the High Current Cutoff setting and
Sectionalizing Mode features overlap. It starts where the High Current Cutoff setting
is equal to or greater than the Sectionalizing Mode Starting Current setting. The
lowest value the High Current Cutoff setting can be set equal to the Sectionalizing
mode starting current is 400 A. To create a zone where the TripSaver II recloser performs
like a pure sectionalizer, set the High Current Cutoff setting to the same value as the
Sectionalizing Mode Starting Current setting. The lowest the High Current Cutoff
setting can be set equal to the Sectionalizing mode starting current is 400 A.
High Current Cutoff
The High Current Cutoff setting is a global setting that applies to all TCC curves
selected. When enabled, the overcurrent elements for all TCC curves including NR curves
will not time and trip on fault current above the value entered. Protection will be provided
by the upstream device. See Figure 106 on page 73.
High Current Cutoff (Enabled or Disabled). Select the Enabled value to enable the
High Current Cutoff setting for all TCC curves.
High Current Cutoff, Current A. Specify current (in amperes) above which the
Overcurrent element of all enabled TCC curves will not time and trip (minimum value:
400; maximum value: 6,300). This value must be less than or equal to the interrupting
rating of the recloser. It also must be equal or greater than the Sectionalizing Mode
Start Current setting to avoid a gap in protection.
Sectionalizing Mode
Sectionalizing Mode. Select the Enabled or Disabled option from the Sectionalizing
Mode pull-down menu list. See Figure 106 on page 73. Note: When toggling this selection
at any time when conguring the sectionalizing settings, all data entered for sectional-
izing settings will be erased.
Sectionalizing Mode Counts. Specify the number of source-side circuit breaker or
recloser trip operations the TripSaver II recloser will count up to before dropping open
(minimum value: 1; maximum value: 9; integer).
Sectionalizing Mode Reset Time, s. Specify the length of time the Sectionalizing
logic waits for an additional sectionalizing event to occur before it resets, in seconds
(minimum value: 0.5; maximum value: 1,000).
Sectionalizing Mode Starting Current, A. Specify the current, in primary amperes,
at which the Sectionalizing mode starts (minimum value: 10; maximum value: 6,500).
Note: This value must be less or equal to the High Current Cutoff setting to avoid a
gap in protection.
