Selecting a Microprocessor Recloser Curve
Emulated Device. Select the Microprocessor Recloser option. See Figure 84.
Figure 84. The Microprocessor Recloser option selected.
Inverse Segment. A new Inverse Segment eld will open after the Microprocessor
Recloser option is selected under the Emulated Device pull-down menu. See Figure 85.
Select various inverse curve segments from the list or select the DefiniteTime option.
The term “S&C,” if present, means the inverse curve segment is an S&C-developed data-
points-based emulation of the TCC curve published by the recloser manufacturer. If
the DefiniteTime option is selected, only the Definite Time-related setting fields will
be displayed.
Note: When an Inverse Segment setting is selected, the curve-selection process is
completed and the Test operation can be copied to the clipboard or saved to a
setpoint file.
Inverse Segment
If an inverse curve segment is selected (e.g., S&C 105), additional elds will open,
as shown in Figure 86.
Figure 86. The additional fields under Inverse Segment option.
Figure 85. The Inverse Segment field.
Minimum Trip, A. Specify the current (in primary amperes) at which the inverse curve
segment begins timing (minimum value: 5; maximum value: 400). Note: Though the
maximum value available is 400 A, the software will prompt with an overload warning
of 40 A for TripSaver II reclosers rated 40 A continuous, 100 A for TripSaver II reclosers
rated 100 A continuous, and 200 A for TripSaver II reclosers rated 200 A continuous.
Some curves may have different ranges for the Minimum Trip setting, as indicated
in the flyover text. This field is mandatory. The Minimum Trip current for 40 A and 100
A continuous TripSaver II reclosers is 5 A. The Minimum Trip current for 200-A continu-
ous TripSaver II reclosers is 10 A.
Time Multiplier. Specify the modifier for the inverse curve segment (minimum
value: 0.01; maximum value: 15). Note: Some curves may have different ranges for the
Time Multiplier setting, as indicated in the yover text. This eld is mandatory.
