Industrial High Voltage NGR Grounding Resistor Switchgears

Technical Specifications：Switchgears

Product Introduction

The Industrial High Voltage NGR Grounding Resistor Switchgears is designed for medium and high voltage power systems to provide neutral grounding protection. It is widely used in 3kV, 6kV, 10kV, and 35kV networks by grounding the system neutral through a neutral grounding resistor (NGR). During a single-phase ground fault, the switchgears limits fault current magnitude, reduces overvoltage risks, and protects transformers, generators, and other critical electrical equipment.

This switchgears features an industrial-grade construction with stable electrical performance and efficient heat dissipation, ensuring reliable operation under high voltage, high temperature, and continuous-duty conditions. The grounding resistor unit can be customized to meet specific grounding current levels and withstand durations according to system requirements. Its compact and well-organized structure allows easy integration into high voltage switchgear assemblies, substations, or standalone grounding systems.By implementing controlled neutral grounding, this NGR switchgears enhances system stability and fault controllability, minimizing equipment damage and outage impact. It is widely applied in industrial power grids, energy systems, and public utility infrastructures as a critical safety protection component in high voltage distribution networks.
