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)

Communication Pathways

How it Works

OMS View and Information

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?

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

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

Future Deployment Utilize AMS radio mesh network Additional benefits Potential Future Device: L&G S610 Additional benefits Oscillographic waveform Supercap – maintenance free Go back to the email that I sent you and find what this device can do.
