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