The advantage of neutral earthing is

Right Answer is: All of the above

SOLUTION

The advantages of neutral grounding are:

(i) Voltages of the phases are limited to phase to ground voltages.

(ii) The high voltages due to arcing grounds or transient line to ground faults are eliminated.

(iii) Sensitive protective relays against line-to-ground faults can be used.

(iv) The over-voltages due to lightning are discharged to the ground, otherwise, there will be a positive reflection at the isolated neutral of the system.
