Neutral Grounding Resistors are used for resistance grounding of industrial power system. They are generally connected between ground and neutral of transformers, generators and grounding transformers.
Neutral Grounding Resistors are used in order to limit maximum fault current to a value which will not damage the equipment in the power system, yet allow sufficient flow of fault current to operate protective relays to clear the fault. Although it is possible to limit fault currents with high resistance Neutral Grounding Resistors, earth short circuit currents can be extremely reduced.
As a result of this fact, protection devices may not sense the fault. Therefore, it is the most common application to limit single phase fault currents with Neutral Grounding Resistors to approximately rated current of transformer and / or generator.
