Apply the SEL-WSO to improve distribution system reliability by remotely monitoring circuits for faults and outages. Using centrally reported data, you can dispatch line workers directly to the faulted line section, reducing outage durations by 50 percent or more. You can also periodically log circuit load data for system analysis and monitor your distribution system from a central location.
Remote Fault Monitoring—Receive wireless indication of fault status from the SEL-WSO to pinpoint the fault location before dispatching troubleshooting crews. The SEL-WSO uses the AutoRANGER trip logic for simple integration with existing protection schemes. After detecting a fault, the SEL-WSO alerts personnel of the affected area with an exception fault report.
Outage Indication—Identify de-energized sections of the circuit with exception outage reports. After the outage, the SEL-WSO automatically sends a restoration report indicating when the line section is re-energized.
Feeder Reconfiguration—Install near remote-controlled, motor-operated switches to provide information for feeder reconfiguration.
Momentary Event Detection—Detect momentary faults, momentary outages, disturbance events, and load pickup events to improve system reliability.
Load Monitor—Approximate circuit loading with average or peak load data refreshed every 24 hours.
Note: Consult factory for available radio solution.
