High-Resistance Grounding Solutions Enhanced with Stainless Steel Grid Technology

Aiming to mitigate arc flash hazards and protect critical transformers, Ruisite has announced a significant upgrade to its Neutral Grounding Resistor (NGR) portfolio. The new NGR series is designed to limit ground fault currents in industrial power systems, effectively reducing the risk of equipment damage and unplanned downtime.

The upgraded resistors feature a corrosion-resistant stainless steel grid element, offering superior thermal stability and longevity compared to traditional cast iron or steel alloys. Available for systems ranging from 480V to 72kV, these units are engineered to withstand severe fault conditions while maintaining precise let-through current thresholds.

"In industrial environments, a single phase-to-ground fault can cause catastrophic damage to generators and transformers if not properly limited," explained [Name], [Title]. "Our new NGR design not only ensures compliance with IEEE 32 standards but also simplifies maintenance with a modular construction that allows for quick element inspection and replacement without disassembling the entire unit."

To enhance safety, the units are housed in weatherproof, high-strength aluminum enclosures with integrated remote monitoring terminals, allowing facility managers to track ground fault status from centralized control rooms.
