Selective Instantaneous Feeder Trip (SIFT) on 2nd Ground Fault
Mitigate 95-98% of arc flash incidents on 1st phase-to-ground fault
Assisted fault location through pulsing system and indication/alarm of faulted phase and feeder
Resistor integrity monitoring. It continuously monitors neutral and resistor continuously to meet the new CSA code requirement.
Time Selective feeder isolation. Feeders can be programmed to trip on 1st fault, 1st with time delay, trip on 2nd fault. It allows the user to set priority levels

According to IEEE 242-2001 Section 8.2.5. Ungrounded Systems: A second ground fault occurring before the first fault is cleared results in a phase-to-ground-to-phase fault, usually arcing, with current magnitude large enough to do damage, but sometimes too small to activate the overcurrent devices in time to prevent or minimize damage.
On standard HRG systems, a second ground fault on a different phase will lead to a phase to ground to phase fault requiring the entire system to shut down with loss of continuity and possible losses of material in process.
High Resistance Grounding is a proven technology that provides process continuity even under a single ground fault condition.
The SMART HRG from I-Gard is the only HRG system that ensures process continuity of your most critical processes even under second ground fault conditions.
The SMART HRG system offers feeder indication and second fault protection which ensures that your most critical process is operational at all times, providing an opportunity for increased revenue.
The SMART HRG system can be configured with the time delay feeder trip.
Feeder indication of a ground fault shortens the time needed to find a fault and removes personnel from the risk involved in starting the search at the main switchgear.
The SMART HRG solution offers HRG and Arc Flash Mitigation functions in the same system.
