1.0 INTRODUCTION
1.1 BACKGROUND OF THE STUDY
The unstable power supply in Nigeria has been an issue ofgreat concernto the dwellers [Agbetuyi et al, 2017]. This retards developmentas well as negatively affects other realms of life in general.As a measure to overcome this, the use of generator has beenadopted by the general masses. At the time of the powerfailure,manualchangeoverfrommainstogeneratorimposes a lot of challenges which needs solution [Agbetuyi et al, 2017]. Thesechallenges include the physical need for the presence of apersonforswitchingonandoffthegeneratorwiththeaccruedinconveniencesofstayingawake,phonecallsorclimbingdownandupthe stairstostartoroffthegenerator.
Other challenges include cost in running of the generator notknowing that power has been restored and the risk of electricshock. Different technologies have, however, been designedand implemented for the purpose of overcoming the abovelisted challenges. Unfortunately, these technologies still posedifferent short comings which still need solution. The designandimplementationofathree phase auto monitoring and switching system aim at overcoming the above limitations as well asaddingothernecessaryfeatures.
Industrialautomationisnecessaryintoday'sworld.Automationminimizeshumanefforts.Ourtimeiswellusedbecause of automation. Production is fast growing. Due toautomation, the cost is reduced. Earlier, when we are talkingaboutautomateddevicesthatcoulddoanythingattheinstigationofacontroller,wearelookingintothefaceofthefuture, but it has become a reality today. An automateddevicecan replacea goodmanpower.
Control of phase load is very much needed in Industry 3.Many machines are used in industry.There are devicesavailable on the market in today's world to control onesingleloadatatime.Thissystemcansimultaneouslycontroltwoloads.Thissavestime,spaceand cost.

Under voltage and overvoltage,machinefailureispermanent.Electricitysometimesbecomes one phase. It's very high to repair costs. To avoidthis, the machines must be protected. We are using loadcontroldevicesforthispurpose.

Some wise scientist once said control system is a system where the machine can be shut down whenever we want. This isthe difference between machine controlled and machine uncontrolled. Our project is to make efficient and dynamic this controlsystem.
1.2 PROBLEM STATEMENT
Due to inconsistent supply of power, there is a growing need for an alternative source of power supply. This has led to heavy capital investment in a bid to suppress power failure and ensure regular power supply for the industry, hospitals, schools and homes. The problem of power failure can be checkmated with the use of stand-by generating set.
In today’s world, there is a continuous need for automatic appliances with the increase in standard of living, there is a sense of urgency for developing circuits that would ease the complexity of life.
The project is designed to operate or control an electrical load multiple number of times as per the program. It overcomes the difficulties of switching the load ON/OFF manually.
1.3 AIM AND OBJECTIVE OF THE PROJECT
AIM
The main aim of this work is to design a device that will overcome power fluctuation phase interruption by switching next most healthy available phase to feed the equipment, and systemcancontrolandcheckthestatusfromanywhereintheworld using GSMmodule.
OBJECTIVES
The objectives of this work are:
- To provide a means of switching from one phase of AC mains to another in the case of failure in the existing phase.
- To sense any abnormal condition inany of the phases which may be low voltages, high voltages orblackouts.
- To automatically disconnects the load fromthe mains source when there is any abnormality and transfers ittothestandbygeneratorsource.
- To controlandcheckthestatusfromanywhereintheworld using GSMmodule.
1.4 LIMITATION OF THE PROBLEMS
In the course of designing this project, different kinds of problems were notice such as:
- Difficulty in troubleshooting with circuit without the circuit diagram
- Difficult in wiring because of the strong wiring the project required.
- It requires maintenance because they involve less complex components, particularly in terms of testing maintenance and replacement part.
- The cost of designing the device is higher than that of the manual selector.
- Operating voltages: 220V-240
- 16A is the maximium load it can handle.
1.5 APPLICATIONS OF THE PROJECT
This device provides constant power supply in our:
- Homes
- Workshops
- Worship centre (such as churches or mosque)
- Offices
- And any other places that electrical energy is been used
1.6 DEFINITION OF TERMS
Power Outage / Power Failure: A power outage is the loss of the electrical power network supply to an end user.
Automatic Changeover: is device that automatically transfers power from generator supply to PHCN supply when available and stops the generator without human intervention.
Voltage monitoring:To determine if a phase imbalance is present.
Switching system:Collection of switching elements arranged and controlled in such a way as to set up a common path.
1.7 METHODOLOGY
To achieve the aim and objectives of this work, the following are the steps involved:
- Study of the previous work on the project so as to improve it efficiency.
- Draw a block diagram.
- Test for continuity of components and devices,
- programming of microcontroller
- Design and calculation for the changeover was carried out.
- Studying of various component used in circuit.
- Construct a digital changeover circuit.
- Finally, the whole device was cased and final test was carried out.
