Product Description
Neutral Grounding Resistors are used for grounding of industrial power system. They
are generally connected between ground and neutral of the 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 Groundi1ng Resistor, 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 low resistance
Neutral Grounding Resistor to approximately rated current of transformer and or
generator.
