S&C 6800 Series User Manual

Fault-Interrupter Option (only applicable to Vista switches)
When the Vista Underground Distribution Switchgear includes fault-interrupting
positions, select the Present state. When a fault interrupter trips open, the
OVERCURRENT FAULT indicator ashes, the LCD displays a message, and the switch
control makes entries on the Diagnostics>Fault Info and Logs>Status Point Log
screens. The condition clears when the fault interrupter is closed.
Current Sensor Ratio
S&C Scada-Mate Switches have several current ratings. For Scada-Mate Switches rated
for 600 amps, or 900 amps continuous current, select a Current Sensor Ratio setting of
600:5. For Scada-Mate Switches with a continuous rating of 1200 amps, select a Current
Sensor Ratio setting of 1200:5. The default setting is 600:5.
Note: After entering the Current Sensor Ratio setpoint, click on the Apply button
before entering the new Current Magnitude setpoints. If the new Current Sensor
Ratio setpoint is not applied before entering new Current Magnitude setpoints, when
clicking on the Apply button, the default Current Magnitude setpoints for the selected
Current Sensor Ratio setpoint will replace the Current Magnitude setpoints entered.
Changing the ratio from 600:5 to 1200:5 or back will change values of the following
settings, so be sure to review each setting after changing the Current Sensor Ratio
value:
• Setup>General>Sensor Cfg screen: The Current Magnitude Poles 1, 2, and 3 setting
changes to 240 if the ratio changes from 600:5 to 1200:5, or the setting will change to
120 if the ratio changes from 1200:5 to 600:5.
• Setup>General>Sensor Cfg screen: The Dual Overhead software has two Current
Magnitudes for Poles 1, 2, and 3 settings.
• Setup>General>Fault Detection screen: The Phase Fault Detection Current Level
setting changes to 1600 if the ratio changes from 600:5 to 1200:5, or the setting will
change to 800 if the ratio changes from 1200:5 to 600:5.
• Setup>General>Fault Detection screen: The Ground Fault Detection Current
Level setting changes to 200 if the ratio changes from 600:5 to 1200:5, or the setting
will change to 100 if the ratio changes from 1200:5 to 600:5.
• Setup>General>Fault Detection screen: The Dual Overhead software has Phase
Fault Detection and Ground Fault Detection levels for both Switch 1 and
Switch 2.
When using a 1200-ampere device with the IntelliTeam SG Automatic Restoration
system, be sure to configure the appropriate Maximum Capacity settings for the system.
The default setting is 600 amperes.
When using a 1200-ampere device with the IntelliTeam SG Automatic Restoration
system and the Phase Loss Isolation feature, be sure to configure the appropriate
Phase Loss Protection Current Threshold setting for the system. The default setting
is 600 amperes.
Selecting a sensor ratio changes the defaults shown on the Setup>General>Sensor
Conf screen and on the Setup>General>Fault Detection screen. The default information
changes immediately when a Current Sensor Ratio setting is selected. After entering
the Current and Voltage Magnitude settings and the Current and Voltage Phase
data for all poles, click on the Apply button to activate the settings.
