Neutral Earthing/Grounding Resistor

Neutral Earthing/Grounding Resistor


Most power distribution networks have their neutral line connected to earth in order to support important currents if a fault occurs.

In order to avoid the potential damage such faults can create, a neutral earthing resistor (or neutral grounding resistor) is fitted between the neutral and earth in order to limit the current and give automatic electrical protection devices enough time to react.

Neutral earthing resistors ensures repeatedly and permanently protection of substations and their components, avoiding costly repairs or replacements.



The experience METAL DEPLOYE RESISTOR has gained by installing thousands of neutral earthing resistors around the world together with the flexibility of our technology and the robustness of our products allow us to meet a large range of requirements.
