in 3ph 415 vac 4wire system the neutral used for 1ph electrical equipment power supply. i.e. nominal voltage 230V 1 ph can be obtained between any one phase and the neutral.

Answer / siva naik

As to the domestic loads i.e lightning loads required the
neutral bcz of This High voltage supply its being connected
with the distribution substations here this voltage is being
step down low voltage by using transformer. Normally the
power transformer primary is formed in delta connection to
avoid the leakage currents and its secondary is formed in
star connection. as required above with the same.
Neutral & Earthing are tied together. neutral its carrying
charging current also acts as return path

Answer / wafiiq

We use 3PH 4 Wire system for secondary side (LV) side of
distribution transformers. The first 3 wires are the three
phases while the 4th wire is the neutral. Grounding the
neutral, a process known as system earthing, will allow
single phase users to have single phase supply from the
distribution transformer, i.e. nominal voltage 230V can be
obtained between any one phase and the neutral. Thus, by
grounding the neutral, we are making sure that it remains
at 0V, i.e. at the earth potential. As for 400V, is simply
the line voltage, between any two phases.
