Voltage Unbalance Reduction in Three Phase Distribution System
voltage unbalance exceeding more than 2 percent in three-phase systems can cause current unbalance among the windings. these, in turn, can cause an increase in winding temperature and an overheating problem that can be harmful to the lode.

Voltage Unbalance Reduction in Three Phase Distribution System
Project Area of Specialization RoboticsProject Summaryvoltage unbalance exceeding more
than 2 percent in three-phase
systems can cause current
unbalance among the windings.
these, in turn, can cause an increase
in winding temperature and an
overheating problem that can be
harmful to the lode.
To run three phase lode without any
interruption.
protection of three phase load avoided
unbalance due to undervoltage .
To dynamically reduce voltage unbalance
(VU) along low voltage distribution feeders,
a distributed intelligent residential load
transfer scheme is proposed. In this
scheme, residential loads are transferred
from one phase to another to minimize VU
along the feeder.
First we convert single phase supply in to three
phase supply.
Then pass these three phase through PT
transform.
Passing the voltage through voltage sensor by
which we can regulate the voltage by using
potentiometer.
We can also use controller in this circuit which
can control all the voltges.
A relay circuit is connected to controller
which we can use it for automatically
switching. Load are connected with relay.
When voltage on one lode become
unbalance the relay module can atomically
switch off and convert the load on the
second load when fault remove from phase
one than lode are automatically re-shifted
from second load to the first load.
Avoid undervolt condition due to increase
of load
Efficiently shifting of phase
Provide protection of three phase due to
over voltage
To make Accurate system as possible
using available resources
it will be deliver in to hard ware from
This project is used whir three phase load is
running wither it is in domestic levels or
industrial levels .
Can b used in as protection of three phase
load.
Three phase load can be run in any power
interrupt
