Arc Flash

IT HAPPENS IN AN INSTANT.
THE CONSEQUENCES ARE SERIOUS.
THE MOST COMPLETE SOLUTION IS HERE. NOW.

Arc Flash Incidents hospitalize 5-7 workers per day in North America and severely impact processes and profitability with lost production costs averaging $20,000 per incident, equipment damage averaging $50,000 per incident and medical costs significantly higher.

An arc is developed within milli-seconds and leads to the discharge of enormous amounts of destructive energy. The energy discharged in the arc is directly proportional to the square of the short-circuit current and the time the arc takes to develop. The damage resulting from an arc short circuit depends on the arcing current and the time. Reduce the time required to detect the arc and stop the current flow and you reduce the damage and impact of the hazard.

Reduce the Time

Reduce the Damage

Reduce the Hazard

35 ms:

no significant damage to persons or Switchgear, which can often be returned to use after checking the insulation resistances

1.27 Cal/cm2
NFPA Hazard/Risk
Category 0

100 ms:

limited or no damage, requires cleaning and possibly some minor repair.inverse

3.23 Cal/cm2
NFPA Hazard/Risk
Category 1

500 ms:

significant damage to equipment and injury to personnel.

18.1 Cal/cm2
NFPA Hazard/Risk
Category 3

 

The arc burning time is the sum of the time to detect the arc and the
time to open the correct breaker.
*Based on 50kA maximum bolted fault current on a 480 volt solidly grounded system.


THE ONE TWO PUNCH

1. DETECT/PROTECT

You can protect your plant, processes and people with I-GARD’s highly effective High Resistance Grounding Systems. I-GARD’s HRG systems can detect the ground fault, signal an alarm and locate the affected branch or feeder removing maintenance personnel from the dangers of higher fault currents. A range of systems allows you to tailor your protection to your specific application.

2. MITIGATE

The I-GARD FALCON provides arc flash mitigation at the speed of light. It is the industry’s fastest arc detection system using adjustable light sensitivity to reduce arc-flash energy with fast detection and tripping, under 1ms.

I-GARD offers you the most complete solution to protect your people, plant and profits. The investment in total protection is an insurance policy that just makes good business sense.

Use our ROI Calculator to see the investment and the payback on total protection.

I-GARD ARC FLASH ANALYSIS

An I-GARD ARC FLASH ANALYSIS is the starting point. Our ARC FLASH ANALYSIS will calculate your Risk using IEEE and NFPA equations and methods and develop a comprehensive protection plan to achieve a safer environment for your people and plant.

Get the details. Then, get the protection. The time to contact us is today ... before you have a problem.
