S&C 6800 Series User Manual

Switch Control Setup
An active Hot Line Tag (HLT) mode inhibits closing by: a front panel switch command,
a SCADA command, a remote IntelliLink Setup Software command, or automatically by
the IntelliTeam SG Automatic Restoration System.
The Hot Line Tag mode does not prohibit a Scada-Mate Switching System hotstick
operation to close the switch.
An active HLT mode on an open IntelliTeam SG system switch takes it, and the teams
it is a member of, out of the Ready state. When the HLT mode is cleared, the switch and
the teams will be restored to the Ready state if the switch is in the Normally Open
mode. If the switch is in the Normally Closed state, and then opened to set a HLT mode,
then the HLT mode must be cleared, the switch closed, and the manual operation cleared
before the team(s) will go back to the Ready mode.
Setting a Hot Line Tag
The Hot Line Tag mode can only be set on a 6801 switch control with an open Scada-Mate
Switch. A closed switch must be opened before the HLT mode can be applied. The Hot
Line Tag mode can be set with:
• A congurable button on the faceplate
• Faceplate navigation to the LCD DISPLAY: “8. User Select Menu” and activating the
HLT mode
• A SCADA command by DNP Control point 8 or 9
The HLT mode can only be cleared by the command type used to set it.
Reporting a Hot Line Tag Configuration
On the Logs>Historic Log screen, the event is either “Hot Line Tag Active” or “Hot Line
Tag OFF.” If the HLT mode was set from the faceplate, another event is reported, “Hot
Line Tag Set Local” and Data 2 = “FP.” If the HLT mode was not set from the faceplate,
another event is reported, “Hot Line Tag Set Remote,” and Data 2 is “ILink,” when set by
IntelliLink software, or Data 2 is “SCADA” when set by a SCADA command.
When the HLT mode is active; the LCD only displays “Hot Line Tag Active.” However,
the front panel arrow buttons still navigate the LCD menu, so the HLT mode can be
turned off with a command on the LCD display.
When the HLT mode is active, the ERROR LED is on. When the HLT mode is cleared
and no other error conditions are active, the ERROR LED will be off.
Hot Line Tag
The Shots-to-Lockout feature allows a field technician or SCADA operator
to test a potentially faulted line by reducing counts-to-trip to either 1 or 2 for a
specied time period. When the circuit is de-energized by a source-side protective
device (recloser, breaker, etc.) and the switch control sees the transition from voltage
present to loss of voltage, the switch control opens the switch immediately. This allows
the faulted line segment to be isolated and prevents the source-side device from reclosing
into a fault multiple times.
NOTICE
If the source-side device opens and recloses very quickly, sensors on the load
side of the switch may not have enough time to sense both the voltage increase
(when the switch closes) and the voltage loss (when the source-side device opens)
before the source-side device recloses. Under these conditions, the switch control
cannot carry out a Shots-to-Lockout function, except during a transfer event. Always
orient the switch so the sensors are on the source side for best results.
