Page 9: Faceplate
Operation Faceplate The 6800 Series faceplate (Figure 2) includes an alphanumeric display, LEDs and touch switches that allow you to monitor and control the line switches and switch-control operation. To conserve battery power, the switch control turns off power to the faceplate LEDs and LCD screen when the enclosure door or low-voltage cabinet door is closed. -
Page 10: Faceplate Led Indicators
Operation Faceplate LED The faceplate includes the following LEDs. See Figure 2 on page 9. Indicators Overcurrent Fault Indicator The LED is on when the switch operator detects an overcurrent condition on any phase. Depending on the configured Fault Indicator Reset Strategy on the Setup> General>Fault Detection screen, the LED is off when the overcurrent condition ends. - Page 11 Operation Battery Low Indicator The LED is off when the battery system is working normally and the battery is charged. The LED is on when battery power is low. It is normal for this LED to be on when the switch control is operating on battery power and the battery is nearly exhausted. The battery may be defective when this LED is on and ac power is also on (the battery normally would have an adequate charge).
-

Operation Automatic Operation Disabled Indicator This LED is on when automatic operation of the switch control is in the Disabled state. Faceplate Switches Data Scroll Keys Use these switches to scroll and enter LCD screen data. Battery Test Switch This switch starts a battery test. The test lasts approximately 30 seconds if the control is operating on battery power or three minutes if the control is operating on ac power. -

Operation Automatic Restoration Switch Press the CHANGE button to toggle the Automatic Restoration mode to the Enabled state. Press the CHANGE button to toggle the Automatic Restoration mode to the Disabled state. This switch affects automatic operation of both line switches, if applicable. When the IntelliTeam SG Restoration mode is in the Disabled state on the IntelliTeam SG>Team Summary screen (for both switches, if applicable), the AUTOMATIC RESTORATION switch will have no effect. -

Page 17: Power Management System
Operation Power Management Power Supply/Control I/O module System The Power Supply/Control I/O (PS/IO) module is a highly-efficient computer-controlled, uninterrupted power-supply system specifically designed to meet the specialized power requirements of automated electric power distribution equipment. The PS/IO module provides steady-state current flow for switch-control operation, pulsed current flow for communication equipment, and occasional large current surges for line-switch operation. -
Page 18: Battery Management
Operation ANALOG PWR This LED is on when power is supplied to the analog processors. It is located at the middle of the board on the top. Battery Management The battery-management system ensures the switch control can operate the line switch with available battery capacity and provides advanced warning of a weak battery condition before the switch cannot be operated. -
Page 19: Battery Care And Maintenance
Operation • Battery Is Disconnected on AC Power—When the battery voltage falls outside the proper range 22.25 - 30.5 Volts (for a 24-Vdc battery), or 33.375 - 45.75 Volts (for a 36-Vdc battery) while the switch control is operating on ac power (or sensor power, if applicable), the switch control disconnects the battery from the system, turns off the BAT ON LED (on the Power Supply/Control I/O board), and sets the Battery Bad DNP Status point. -

Page 21: Switch Control Operation
Switch Control Operation Operational Overview This section explains how the switch-control components work together to detect and respond to overcurrent faults and voltage outages. Signal Processing The switch control has separate electronic paths to accommodate the different requirements of peak and normal operating-current measurements. For normal operat- ing- current measurements, full scale is 800 amps RMS. - Page 22 Switch Control Operation For switches with one voltage transformer for voltage sensing and control power and three CVMI current sensors, the sensor-conditioning module must always be configured with the wye jumper. Voltage sensing and reporting is determined by the way the voltage transformer is connected: phase-to-phase (delta) or phase-to-neutral (wye).
- Page 23 Switch Control Operation Overcurrent Fault & Voltage Loss Detection Overcurrent faults are measured with peak-current detection hardware for phase faults and separate true-RMS amplitude-detection hardware for the harmonic-sensitive neutral current faults. To determine whether an overcurrent fault exists, the switch control compares the sensed current to setpoint values that define the fault current level and fault duration.
-
Page 24: Inrush Restraint
Switch Control Operation Ground Overcurrent Detection The switch-control hardware measures ground current as the analog-vector sum of the three individually sensed phase currents. A very accurate harmonic-independent true RMS detecting circuit integrates the analog-vector sum over several cycles. The multi-cycle integration produces a slight response-time delay that is inversely propor- tional to the magnitude of the change in ground current. - Page 25 Switch Control Operation • When the switch is closed, the switch control starts the Phase Current Inrush Restraint timer and the Ground Current Inrush Restraint timer. • When both the Current Inrush Restraint Multiplier values are set to Time Block mode, the switch control ignores all overcurrent conditions until the Inrush Restraint timers expires.
-
Page 26: Switch Control Automatic Operations
Switch Control Operation Switch Control A 6800 Series Switch Control can perform several automatic operations: sectionalizing, phase-imbalance protection, phase-imbalance protection with automatic reclose, and Automatic Operations the one- or two-shot-lockout of a faulted circuit. The appropriate value for the Loss of Voltage Threshold setpoint must be entered for the automatic operation features to work correctly. - Page 27 Switch Control Operation When the counter reaches the setpoint value before the timer expires and the problem was a load-side fault, the control trips open the switch. When the counter reaches the setpoint value before the timer expires, the team is ready, and the problem was a source-side fault, the control trips open the switch.
- Page 28 Switch Control Operation NOTICE Be sure to select a conservative value for the Phase Loss Protection Current Threshold setting that is clearly below the loadbreak rating for the line switch� • Use either the faceplate AUTOMATIC OPERATION ENABLED/DISABLED switch or a SCADA command to enable the Automatic Operation mode.
-
Page 29: Automatic Load Transfer
Switch Control Operation The switch control recognizes that the source-side device opened. When the Number of Shots Required for Lockout value is set to “1,” the switch control immediately trips open the switch. When the value is “2,” the switch control waits until the source-side device recloses and opens a second time, and the switch control trips open its switch. -
Page 30: Loading Restrictions
Switch Control Operation Any team member that witnesses an event tells all other team members and the coach about the event. The transmission includes a sequence number, the nature of the event, and which team member made the report. All members continually monitor for this report. When the report requires local team restoration, the coach visits the other normally closed team members to verify they are now open and then follows the alternate source sequence list, visiting team members that could become an alternate source. -
Page 31: Contracts
Switch Control Operation When a team is in the reconfigured state and the alternate source experiences a new event, the team can look for a new alternate source, if available, to supply its line segment. A normally open switch in a source/substation location must have the voltage sensors on the substation side. -

Switch Control Operation • The contract reaches the source/substation switch agent and the agent checks for available excess capacity (When the contract request exceeds excess capacity, the agent declines the contract and returns the contract directly to the originating contract agent.) •... -

Switch Control Operation • Use either the faceplate AUTOMATIC OPERATION ENABLED/DISABLED switch or a SCADA command to enable the Automatic Operation mode. Prohibit Restoration This feature disables the team Automatic Restoration feature (automatic closing of switches) in case of emergency or for circuit anomalies where restoration would be undesirable. - Page 34 Switch Control Operation When the Prohibit Restoration mode is active, view the Logs>Status Point Log screen to determine whether this was the result of a SCADA command or a Prohibit Restoration Timer operation.
