FAQ
Q: What is the main function of the Neutral Earthing Resistor?
A: The Neutral Earthing Resistor is mainly used to limit fault current when a grounding fault occurs in a power system. It helps keep the fault current within a relatively controllable range while providing suitable operating conditions for relay protection and fault detection.
Q: Why is the Neutral Earthing Resistor installed at the neutral point?
A: The neutral point is an important connection point in the grounding system of a power system. Installing the Neutral Earthing Resistor between the neutral point and earth creates a defined grounding path that can appropriately limit fault current when a grounding fault occurs.
