    Installation Power Supply/ Control 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 I/O Module requirements of automated electric power distribution equipment. The PS/IO module provides steady-state current flow for switch control operation, pulsed current flow for communications equipment, and occasional large current surges for line switch operation.
  • Page 14 Installation The switch control continuously monitors the battery voltage. In addition, it tests the battery at regular, scheduled intervals. The interval depends on the power conditions: • During battery discharge, the test is run hourly. • After a power outage, the test is run every two hours for 24 hours to monitor the bat- tery status while the battery is recharged.

  • Page 15: Battery Care And Maintenance

    Installation Battery Care and Typical battery life for 5800 Series controls is five to seven years. The battery should be replaced when capacity is reduced to 80% of capacity when new. Increased temperature Maintenance accelerates battery aging, so installations in warmer climates will have a shorter battery life.

  • Page 17: Switch Control Operation

    Switch Control Operation This section explains how the switch control components work together to detect and respond to “faults” and voltage outages. Signal Processing The switch control includes separate electronic paths to accommodate the different requirements for peak versus normal operating current measurements. For normal operating current measurements, full scale is 800 amps RMS.

  • Page 18: Voltage Sensing For S&C Switches

    Switch Control Operation Voltage Sensing for The 5800 Series control software supports 15-kV, 25-kV, and 34.5-kV S&C switches. S&C Switches The nominal voltage sensor ratios for the line switch(es), with corresponding maximum voltage levels, are shown in the Table 1.

  • Page 19: Ground Overcurrent Detection

    Switch Control Operation Phase Overcurrent Detection Phase overcurrent conditions are sensed using a combination of analog and digital techniques. The switch control provides fault detection with a resolution of 1/3-cycle and peak values of approximately 4000 amps RMS. Overcurrent measurements are accurate to 0.5% of full scale, excluding sensors.

  • Page 20: Voltage Loss Detection

    Switch Control Operation Voltage Loss The switch control checks the voltage on all three phases at 50-millisecond intervals. Any voltage drop below the Loss of Voltage Threshold setpoint is considered a voltage Detection outage. Inrush Restraint The Inrush Restraint feature prevents phase or ground overcurrent conditions, which can occur during outage restoration (hot or cold load pickup) from falsely indicating a “fault.”...

  • Page 21: Automatic Operations

    See S&C Instruction Sheet 1041-530 for additional details. Automatic Operations The 5800 Series switch control can carry out several automatic operations: sectionalizing, phase imbalance protection, phase imbalance protection with automatic reclose, and one- or two-shot-lockout of a faulted circuit. These are explained below.

  • Page 22: Phase Loss Protection

    Switch Control Operation (e) If the Sectionalizer Reset and Extended Voltage Loss Time timer expires before the counter reaches the appropriate Recloser Counts to Trip value, the switch control resets the counter to zero. Later voltage losses are considered part of a different reclose sequence. However, if three-phase voltage is not present when the timer expires, an Extended Voltage Loss condition exists and the switch control opens the switch.

  • Page 23: Phase Loss Protection With Automatic Reclose

    Switch Control Operation At the SETUP: Automatic Operation screen, enter values for the Phase Loss STEP 2. Protection Time Threshold and the Phase Loss Protection Current Threshold timers. A Phase Loss Protection Voltage Threshold value can also be entered. Otherwise, the switch control uses the Loss of Voltage Threshold value on the SETUP: Site-Related screen.

  • Page 24: Shots-To-Lockout

    Switch Control Operation Shots-to-Lockout The Shots to Lockout feature allows the field technician or SCADA operator to test a potentially faulted line by reducing the counts to trip to either one or two for a specified time period. If the circuit is then 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.

  • Page 25: Local Shots-To-Lockout

    Switch Control Operation Local Shots-to- To carry out the Shots to Lockout command from the switch control faceplate: Lockout STEP 1. On the first page of the SETUP: Automatic Operation screen, make sure: • The Features Enabled setpoint is set to an option that includes “Sectionalizing.” •...

  • Page 26: Overcurrent Fault Protection

Fault Events Log Click the Overcurrent Fault button on any screen to open the OVERCURRENT FAULT MENU screen, and then click the Fault Events button.
  • Page 27 Overcurrent Fault Protection Phase A OC; Fault current sensed & cleared; Noted The switch control detected an overcurrent fault on Phase A. That overcurrent fault has ended. The switch control is waiting to determine whether voltage will be lost on all three phases.
  • Page 28 Overcurrent Fault Protection Full count reached; Load-side fault; Noted The full count was reached on the recloser operations counter. Because the first voltage loss in the sequence was preceded by an overcurrent fault, as well as all subsequent voltage losses, if the Fault Current Required Before First/All Voltage Loss(es) value is set to “All”, the control will take the appropriate sectionalizing action.
  • Page 29 Overcurrent Fault Protection Phase imbalance w. reclose enabled; Waiting The switch control detected a phase imbalance while Automatic Reclose mode was enabled. The control tripped open the line switch and is now waiting for three-phase voltage to return. Note: When full voltage returns, the control will start the Automatic Reclose timer. When voltage is continuously present for the full count of the timer, the control will reclose the switch.
