How would you supply a single house hold load from a 3-phase supply coming out of a sub-station?..

3-phase supply from a sub-station will be 11kv or
6.6kv.This Voltage is stepped down to 440V by the
distribution Transformer,the distribution transformer has
Delta - Star connection, so in the output side you will hav
neutral line.
Now the phase voltage is 440 V.To supply house hold load we
connect the mains between a phase and neutral

Answer / gopal manda

for only a single house hold load we dont establish three
phase sub station,we establish sigle phase transformer
(5kva,10kva) according to load.for the primary input we
input phase voltage 6.6 kv,one terminal of primary connect
to 11kv phase and other is grounded which is neutral.and we
get 230 volt at secondary.

Answer / fireprs

step down 3-phase supply using step down transformer upto
440 V,then can be used by making scott connection,or by
using it through a diffrent neutral or if it is delta-star
connnected use the neutral of secondary.
