The Gardian is a revolutionary step forward in electrical system protection combining the recognized safety and reliability benefits of high-resistance grounding with the incident energy reduction capabilities of arc mitigation, all in a single product.

With HRG reducing the frequency of arc flash incidents and optical detection reducing the impact, a safer more reliable electrical system is guaranteed with the Gardian.

When a ground fault occurs, the Gardian controls and limits the fault current, provides an alarm that indicates an active fault, enabling electrical personnel to follow a simple sequence to locate and isolate the fault without interrupting the circuit or opening circuit breakers.

When an arc flash occurs, the optical detection system recognizes the hazard initiating the trip signal in less than one millisecond, reducing incident energy levels as well as PPE requirements.
