Grounding Resistors
are designed to provide added safety to industrial distribution systems by
limiting ground fault current to reasonable levels. They are
usually connected between earth ground and the neutral of power
transformers, power generators or artificial neutral transformers. Their
main purpose is to limit the maximum fault current to a value which will not
damage generating, distribution or other associated equipment in the power
system, yet allow sufficient flow of fault current to operate protective
relays to clear the fault.
