Neutral Grounding Resistor (NGR) bus duct connections limit ground fault currents to safe levels while allowing fault detection.

Purpose

• •Limits ground fault current
• •Prevents transient overvoltages
• •Allows sensitive earth fault protection
• •Reduces equipment damage

Specifications

• •Resistance value per system design
• •Current rating for fault duration
• •Stainless steel resistor elements
• •Temperature monitoring and alarms
