To design & fabrication of a hardware which will monitor the performance of the load sharing process by taking power consumed by the load into consideration.

The transformer cannot supply load more than its rated capacity.

So, by introducing another transformer, reduces the load on the transformers.

Two transformers are used - Main transformers & Slave transformers.

Here 2 transformers are connected through a relay.

Load is directly connected to secondary of the main transformer as well as slave transformer.

A sensor circuit is used to log data from the main transformer .

If sensor found the overvoltage condition, immediately the slave transformer will be connected in parallel to the main transformer & the load is shared.

Transformers Transformer is a static device which consist of two or more stationary electric circuit interlinked by a common magnetic circuit for the purpose of transferring electrical energy between them.

The transfer of energy from one circuit to another takes place without change in frequency. In this project we are using 2 transformer- main & slave transformers. Rating of both the transformers- 230/12v & 3A.

Both transformers of same rating are connected in parallel through a relay.

Regulated power supply-

A regulated power supply is embedded circuit, the function of which is to supply a stable voltage.

The output is dc(direct current). This regulated output is supplied to comparator IC. To make Regulated power supply we use- - Diodes -Capacitors(4700F&25v) -IC 7805 voltage regulator.

Transformer- steps down high voltage AC mains to low voltage AC.

Rectifier- converts AC to DC, but the DC output is varying.

Filter- smooths the DC from varying greatly to a small ripple.

Regulator- eliminates ripple by setting DC output to a fixed voltage.

Comparator-

LM324 operational amplifier is used as a comparator in this project.

It is used to compare load with the standard load capacity of a transformer.

When the load capacity exceeds the capacity of load it give signal to relay to switch on the slave transformer in parallel to the main transformer.

Relay-

A relay is an electrically operated switch.

Relays allow one circuit to switch a second circuit which can be completely separate from the first.

In this project we are using electromagnetic relay consists of a multi-turn coil, wound on an iron core, to form electromagnet. When the coil is energised, by passing current through it, the core becomes temporarily magnetised. The magnetised core attracts the iron armature.

Load Bank-

In this project we are using set bulbs as a load, connected at the secondary of a transformers.

Transformer rating is= 12VX 3A = 36 VA or watt Load capacity(rating) = >36watt ~ 3- 10watt bulbs & 1- 2 watt
