What is DA?What is DA? Field systems that:
Monitor equipment Remotely control devices Automatically detect and isolate faults Automatically restore electric service to customers
Software platform for: Demand response Energy delivery optimization Support Electric Vehicles and Solar Technologies Other applications
DA systems will be integrated with DMS to further optimize systems operations

Feeder 2
Substation
• Breaker at the substation clears the fault
• All customers on the feeder lose power
• Crews need to patrol the entire length of the feeder to locate the fault

Feeder 2
Substation
• Breaker at the substation clears the fault
• DA locates the fault and isolates the faulted segment of the feeder

Feeder 1
Feeder 2
Substation
• DA reconfigures feeders, closes the breaker and restores power to all unfaulted segments
• Crews can be dispatched directly to the faulted segment
