Advanced TCC Curve Setup
(optional). (Click on the
Advanced TCC Curve Setup
button to expand/collapse area.) See Figure 74.
Figure 74. The Advanced TCC Curve Setup fields.
Low Cutoff
(checkbox). Select this checkbox to enable low-current cutoff.
See Figure 74.
Low Cutoff Current, A.
Specify the current (in primary amperes) below which the
inverse curve segment is truncated. The Low Cutoff current will then be the actual
minimum trip current.
Note:
This value must be greater than the minimum trip current of
the inverse curve segment and smaller than the
High Current Cutoff
setting (minimum
value = 5; maximum value = 600). See Figure 74.
Definite Time 1
(checkbox). Select this checkbox to enable the
Definite Time 1
element. See Figure 74.
Note:
The
Definite Time 1
element must be enabled before the
Definite Time 2
element can be enabled. If the
Definite Time 1
element is deselected,
the
Definite Time 2
element is deselected automatically.
Definite Time 1 Current, A
. Specify the current (in primary amperes) at which the
Definite Time 1
element picks up (minimum value = 5; maximum value = 6,300). See
Figure 74.
Note
: This value must be greater than the Minimum Trip current, greater than
the Low Cutoff current, less than or equal to the interrupting rating of the recloser, and
smaller than the
High Current Cutoff
setting.
Definite Time 1 Time, s.
Specify the time delay (in seconds) after which the
Definite
Time 1
element trips (minimum value = 0; maximum value = 1,000). See Figure 74.
Note:
This value must be less than or equal to time on inverse curve segment at Definite
Time 1 current.
Definite Time 2
(checkbox)
.
Select this checkbox to enable the
Definite Time 2
element. See Figure 74.
Note
: This checkbox is not active unless the
Definite Time 1
element is enabled.
Definite Time 2 Current, A.
Specify the current (in primary amperes) at which the
Definite Time 2
element picks up (minimum value = 5; maximum value = 6,300). See
Figure 74.
Note
: This value must be greater than the Definite Time 1 current, less than
or equal to the interrupting rating of the recloser, and smaller than the
High Current
Cutoff
setting.
Definite Time 2 Time, s.
Specify the time delay (in seconds) after which the
Definite
Time 2
element trips (minimum value = 0; maximum value = 1,000). See Figure 74.
Note:
This value must be less than Definite Time 1 time.
