为了减轻电弧闪光危害并保护关键变压器，瑞斯特宣布对其产品进行重大升级中性点接地电阻（NGR）投资组合。 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.
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.
