S&C 6800 Series User Manual

Switch Control Setup
This setting is configured in the IntelliTeam Designer software and cannot be changed
on this screen. See S&C Instruction Sheet 1044-570, “S&C IntelliTeam® Designer: User’s
Guide.”
For example: If the Maximum Source Capacity value is set to 150 amps and the
Overload Permitted value is set to 150 amps, the PRLM will allow up to 300 amps of
load on that source before shedding load.
Time Overload Permitted
This is the total time that the overload can be above the Maximum Source Capacity
setting before load shedding is triggered. This setting is only applicable when the
IntelliTeam system Post Restoration Load Management options are enabled. This
setting is used along with the Overload Permitted setting to allow temporary overloads
on a specic source. (Range: 0-7,200 minutes; Step: 1; Default: 0) This setting is congured
in the IntelliTeam Designer software and cannot be changed on this screen. See S&C
Instruction Sheet 1044-570, “S&C IntelliTeam® Designer: User’s Guide.”
Overload Qualification Time
This is the time the measured load must be above the Maximum Source Capacity
setting to qualify as an overload condition. When an overload is qualied, the Time
Overload Permitted timer begins timing. This setting is only applicable when the
IntelliTeam system Post Restoration Load Management options are enabled. (Range:
0-250 seconds; Step: 1; Default: 100)
For example: The Maximum Source Capacity setting = 400 amps, the Overload
Permitted setting = 100 amps, the Time Overload Permitted setting = 5 minutes,
and the Overload Qualification Time setting = 50 seconds. If the load goes above 400
amps for 50 seconds, the Time Overload Permitted timer begins timing. If the load
stays between 400 and 500 amps for 5 minutes, a load-shedding event is initiated based
on the configured load priorities, and load will be shed to below the Maximum Source
Capacity value.
Restore to Overload plus Max Capacity
When enabled, this setting allows the IntelliTeam system to restore load up to the
Maximum Source Capacity + Overload Permitted values during an IntelliTeam
system restoration event. This setting is only applicable when the IntelliTeam system
Post Restoration Load Management Options are enabled. (Default: Disabled) This
setting is congured in the IntelliTeam Designer software and cannot be changed on this
screen. See S&C Instruction Sheet 1044-570, “S&C IntelliTeam® Designer: User’s Guide.”
For example: The Maximum Source Capacity setting = 400 amps, the Overload
Permitted setting = 100 amps, and the Restore to Overload plus Max Capacity
setting = Enabled. When there is a restoration event, the IntelliTeam system will restore
up to 500 amps of load (the Max Source Capacity + Overload Permitted settings) for
the configured source.
Default Source Segment Loading
This is the estimated peak three-phase average load (in amperes) of the source-side
segment between the substation-feeder breaker and rst IntelliRupter fault interrupter,
6800 Automatic Switch Control, switch, or recloser. This value is used to estimate the
maximum load in the event that real-time feeder loading data are not available or valid.
(Range: 0-2,540 amps; Step: 10.0; Default: Disabled)
Real-Time Feeder Loading Valid Timer
When real-time feeder loading data are received through SCADA, this congurable
timer starts counting. If the loading data are not updated within the congured interval
(in minutes), loading calculations will default to using the Default Source Segment
Loading value. (Range: 1-60; Step: 1; Default: 20)
