Answer 2

Neutral Earthing Resistors

Neutral Earthing Resistors (NERs) are one of the commonest types of earthing systems in medium-voltage AC distribution networks. Also called Neutral Grounding Resistors, they limit the current that would flow through the neutral point of a transformer or generator in the event of an earth fault. Earthing resistors 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.
