Continuous process manufacturers rely on I-GARD’s High Resistance Grounding Systems (HRG) to help ensure continuity of operation by protecting against over voltages and reducing the risk of arcing ground faults.  

I-GARD HGR's: PATENTED, UNIQUE, DIFFERENT, BETTER
High Resistance Grounding

Protect your plant. Maintain your power. I-GARD'S High Resistance Grounding Systems allow you to detect and locate a ground fault without power interruption.

From Basic to the Ultimate in Protection, I-GARD has an HRG system to meet your needs. With the cost of arcing faults estimated at between $1 billion and $3 billion annually for equipment loss, production downtime and personal liability, you can't afford to take the risk.

A System For Every Application
Which HRG Is Right For You?
