Select a Hydraulic Recloser Curve
The following describes how to confi gure the Hydraulic Recloser curve:
Emulated Device.
Select the
Hydraulic Recloser
option from the
Emulated Device
pull-down menu. See Figure 83.
Figure 83. 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 84.
Figure 84. The Inverse Segment and Coil Rating fields.
Inverse Segment.
Select inverse curve segment from the list. It’s identifi ed as follows:
“x-y”, where “x” indicates the recloser type (e.g., H, L, E, etc.) and the “y” indicates the
specifi c TCC curve (e.g., A, B, C, or D). See Appendix A on page 97 for curve defi nitions.
For example, in Figure 85, for an H recloser, an A curve has been selected.
Figure 85. The Inverse Segment drop-down list.
Coil Rating.
Select a coil rating from the list. For hydraulic reclosers, the minimum trip
current of the inverse segment is twice the coil rating. See Figure 86.
Note:
This fi 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 ampere rating is selected, the curve selection process
is complete and the test operation can be copied to the clipboard or saved to a setpoint fi le.
Figure 86. The Coil Rating drop-down list.
Note:
The
Advanced TCC Curve Setup
feature is not available for the
Hydraulic
Recloser
option.
Select an Instantaneous Curve
An instantaneous curve is a Defi niteTime curve with no time delay. Enter the settings
shown in Figure 87 to confi gure an instantaneous curve. The current at which the
instantaneous curve starts timing must be specifi ed.
Figure 87. An Instantaneous curve should be set exactly like what is shown in this screenshot.
