In neutral earthing case,Current starting flowing through
neutral of transformer or generator in event due to earth
fault and we use resistor for it(NERs).
In body grounding the body(instrument) make electrical
connection with ground.

Answer / Pravesh Kumar Singh

The distance between body earth (PE) and neutral earth (N) should be as short as possible, ideally zero. The purpose of earthing is to provide a path for excess current to flow safely to ground, minimizing potential hazards. However, in some cases, there may be practical reasons why the distance cannot be zero, but it should be kept as minimal as feasible.
