Answer / ahatesham

In urban area total load is large so there is a 3-phase
system from which all 1-phase consumers as well as 3-phase
L.T. Consumers are feeded.
But in rural area total load is low so we can feed all the
consumers by running only a 1-phase line also.
SO IN RURAL AREA 1-phase 230V line runs which feeds all the
consumers , is known as single phasing.

Answer / preitee ranjan

Generally we hv a rule that phase is directly prop. to
operating voltage(efficiency).And we also need low voltage
operation as possible for safety purpose.so for ssi(small
scale industry,house hold)440v/230v is requierd,which can be
implimented using single n multiple phases.but single phase
is efficient(conductor size,no pf conductor)etc.

Answer / k.prakashchandra

To reduce the peak load on the system, single phase supply
is made available in rural areas for single phase domestic
and commercial use only
