what is the purpose of neutral grounding resistor (NER) and why?..

Answer / elizabeth

Neutral Earthing Resistors (NERs) – sometimes called Neutral Grounding Resistors – are employed in medium-voltage AC distribution networks to limit the current that would flow through the neutral point of a transformer or generator in the event of an earth fault. NERs limit fault currents to a value that does not cause any further damage to switchgear, generators or transformers beyond what has already been caused by the fault itself.

what is the purpose of neutral grounding resistor (NER) and why?..

Answer / maqbool

THE purpose of neutral grounding resistor is to limit the
fault current of the system since ground fault current
takes earth as return path

Answer / sajid hussain

Sir I want to install the uat neutral grounding resistor. Where it will connect from and to?. And tell me it's function. Thanks

Is This Answer Correct ?    0 Yes 1 No

what is the purpose of neutral grounding resistor (NER) and why?..

Answer / getdaya@yahoo.com

the fault current in power system depend upon the impedence
value of the system,for neutral grounding which provides
high reactance tot the ps ,and low resistance to the ps,

Is This Answer Correct ?    2 Yes 6 No

what is the purpose of neutral grounding resistor (NER) and why?..

Answer / minal

NGR means Neutral grounding resistor. This is connected to
neutral wire to ground the extra leekage current.
Since in UT,UAT & ST star connection is used, that means
there are 4 wires (R,Y,B & N).Thus neutral is grounded with
a resistor.

Is This Answer Correct ?    7 Yes 15 No

what is the purpose of neutral grounding resistor (NER) and why?..

Answer / ramesh

Neutral grounding resistor generally used in star connected
load in order to reduce the over voltages due to either
switching phenomena or lightning phenomena.

Neutral grounding reactor is another component used for the
same purpose.

Is This Answer Correct ?    7 Yes 18 No

what is the purpose of neutral grounding resistor (NER) and why?..

Answer / subhani

any short circuits occur in stator or rotor then that short
circuit current will limitig and any erath fault occur in
rotor or stator then thats current will also limited value
by depending on resisance value
