Any device is earth-connected due to following reasons:
1) to provide via reference potential, as you know we deal with AC and has got no fixed value.
2) to detect faults. The earth provides a return short circuited path to detect faults.
Neutral is present in WYE only. In WYE connections the RMS value of the phase voltages might start varying as we apply unbalanced load. Grounding/earthing a neutral helps avoiding this variation.
