MISSION
Predict failures. Prevent outages. Protect Lives.
Distribution circuits consist of many components, all of which have a finite service life. When these components fail they create outages, wildfires, and safety hazards. Many common component failures produce distinct electrical signatures detectable with the right equipment at the substation. Utilizing decades of innovation and more than 4,000 circuit-years of data, DFA technology delivers industry-leading capability that enables you to detect and fix underlying circuit issues before they cause an outage.
Make Power System Data Actionable
Data doesn't prevent outages - recognizing problems does. In a two-year field study, communicating reclosers recorded 178 faults on a single circuit but missed the pattern: 44 of them were precursor events, traceable to a single location, warning of a more significant failure to come - in this case, a burned-down conductor.
Â
DFA, monitoring the substation's existing CTs and PTs, recognized the pattern after just a few events and provided alerts over the following months, turning data into actionable information.
​
This case study compares "business as usual" to "business with DFA", and the difference is clear:
​
Without DFA
Dozens of faults, no clear correlation, respond to outage, eventual line on the ground
​
With DFA
Early warning, precise explanation, preempt outage, no line on the ground
​

Technical Benefits
See Failures Before They Happen
Detect and repair failing equipment before it causes an outage, replacing hours of unplanned downtime with brief, scheduled maintenance that maintains system uptime and reliability.
No New Sensors Required
Use PTs and CTs you already have in your substation.
Answers, Not Data
In-substation algorithms automatically convert high-fidelity waveforms into specific, actionable reports and alerts.
