Products Description

The Industrial Neutral Earthing Resistor is a dedicated electrical device designed for industrial high-voltage and low-voltage power distribution systems, mainly connected in series between the neutral points of transformers, generators and the ground. It is fabricated from corrosion-resistant and high-temperature resistant alloy materials, featuring strong overload resistance, high impact resistance and outstanding stability, so it can withstand complex long-term industrial working conditions.Its core function is to limit grounding fault currents of the power system and optimize the grid grounding mode. When a single-phase grounding fault occurs on the grid, it buffers fault surges, suppresses overvoltage, discharges fault currents smoothly, and assists relay protection devices to identify faults accurately. It is a core supporting device that guarantees stable operation of industrial power distribution systems.

FAQ

Q: Will grounding faults cause harm to on-site workers?

A: The Industrial Neutral Earthing Resistor significantly reduces electric shock risks. It lowers the ground fault voltage and step voltage, and works with protective devices to cut off power rapidly, thus better protecting the safety of on-site personnel.

Q: Is frequent maintenance required for year-round non-stop operation?

A: Frequent maintenance is unnecessary. Simple daily inspections for abnormal overheating and strange noises, together with unobstructed ventilation around the unit, support long-term stable operation.

Q: Can it protect transformers against lightning damage during thunderstorms?

A: The Industrial Neutral Earthing Resistor buffers instantaneous high voltage and impulse currents brought by lightning strikes. It lessens lightning-induced damage to transformers and cables and improves power utilization safety during thunderstorm weather.

Q: Are there any differences in protective effects when matched with generators versus distribution transformers?

A: Its core protective functions including current limiting, overvoltage suppression and arc elimination remain identical whether paired with generators or distribution transformers. It provides stable protection for the whole power supply system. Only applicable scenarios differ, with no reduction in overall safety protection capacity.
