3. FCI Devices
Grid advisor 1
Grid advisor 2

4. Current Deployment Grid Advisor 1 (Eaton/Cooper): 99 units
Built-in batteries, harvest line energy to charge
Minimum Line Amps Required: 3 amps
Requires Grid server 1 to communicate with SCADA
Verizon only
Grid Advisor 2 (Eaton/Cooper): 128 units
Replaceable batteries, harvest line energy to charge
TCP/IP direct communication to SCADA
LEDs for visual indicators
Dual-mode modem (Verizon or AT&T)

5. Communication Pathways

6. How it Works

7. OMS View and Information

8. Information in OMS Analog points Digital points
Line amps (last reading and average)
Calculated line voltage
Fault current
Battery voltage
Digital points
Fault indicator (sustained and momentary)
Loss of current
Line current direction
Lower power mode
Normal power mode
Only reports unsolicited messages for sustained fault
Can they report unsolicited messages for temporary faults? Yes
Do you get an alarm for bad/low battery? No but we can
What does E-field mean?

9. Lessons Learned Inconsistent load
Oil field
Water pump
Feeder reconfiguration
Deplete batteries from over-reporting
Lack of event timestamps
Cellular dependency
Coverage
Technology decommision

10. 2016 Deployment 1260 Grid Advisor 2 Overhead Deployment Prioritization
Feeders with Hospitals without existing DA equipment
Install 1 set at sectionalizing device near 50% of customers
Underground Deployment Prioritization
Feeders with at least 12 switchgear
Install set on source side of every 5th or 6th switchgear

11. Future Deployment Utilize AMS radio mesh network Additional benefits
Potential Future Device: L&G S610
Additional benefits
Oscillographic waveform
Supercap – maintenance free
