First of all we need to know ,Why we earth the transformer
neutral,? and the answer is that ,
Transformer has three out put phases and at any time all
these phases loads are not equal, so when the load is
unbalanced on any phase, the current may flow in neutral
line,and to dissolve the current at transformer end we need
to earth the neutral. Neutral pits are used to to provide
best conductive earth.
