Video Case Study: Real-Time Arc Flash Detection and Response
EPRI and Dominion test the DIGITALGRID Safe Service Mode (SSM) feature in 2013.
​In this video, an Arc Flash occurred at 25,000 Amps during a 3 Phase Fault Test. The 480V arcing faults tend to be the most dangerous because they do not self-extinguish. DIGITALGRID Safe Service Mode (SSM) detected the fault within 1 cycle, and the total fault mitigation time was within 4 cycles.

"For ComEd, two key elements of installing a monitoring system on a network transformer are the ease of installation and minimal amount of components needed. Digitalgrid is able to meet both these needs with its network protector master relay."

Our mission is to keep your crews, customers, and equipment safe by modernizing secondary distribution networks.
We can focus our limited O&M dollars on the equipment that needs maintenance.
With the data we collect, we can do condition-based maintenance rather than maintenance based on a fixed-time interval.

We had an incident in the network yesterday which activated DIGITALGRID Safe Service Mode (SSM) on one of our vaults.
Safe Service Mode very likely saved the guy’s life or, at a minimum, prevented a larger flash.

We were dropping Circuits for asbestos removal and had 2 protectors hang up. I sent commands to each unit, and they picked up their signal from an energized Circuit and opened.
To pump and manually trip one of these would take at least 2 hours. I accomplished it in 10 minutes from the comfort of my truck with no exposure to hazards from the manual work for my Crew.
