Selecting a Hydraulic Recloser Curve
The following describes how to congure the Hydraulic Recloser curve:
Emulated Device. Select the Hydraulic Recloser option from the Emulated Device
pull-down menu. See Figure 97.
Figure 97. The Hydraulic Recloser option.
New Inverse Segment and Coil Rating fields will open after the Hydraulic Recloser
option is selected from the Emulated Device pull-down menu. See Figure 98.
Figure 98. The Inverse Segment and Coil Rating fields.
Inverse Segment. Select inverse curve segment from the list. It’s identied as follows:
“x-y”, where “x” indicates the recloser type (e.g., H, L, E, etc.) and the “y” indicates the
specic TCC curve (e.g., A, B, C, or D). See Appendix A on page 123 for curve denitions.
For example, in Figure 99, for an H recloser, an A curve has been selected.
Figure 99. The Inverse Segment drop-down list.
Coil Rating. Select a coil rating from the drop-down list. For hydraulic reclosers, the
minimum trip current of the inverse segment is twice the coil rating. See Figure 100.
Note: This eld is not active unless a hydraulic recloser Inverse Segment option has
been selected. When changing the selection for the Inverse Segment setting at any
time, the coil rating selected will be removed. When the coil rating is selected, the curve
selection process is complete and the test operation can be copied to the clipboard or
saved to a setpoint le.
