DESIGN AND CONSTRUCTION OF 1000VA
AUTOMATIC VOLTAGE REGULATION
ABSTRACT
The design and construction of 1000VA Automatic Voltage Regulator is made to power our Electrical and Electronic devices, supplying them with the normal output voltage which ranges from 100V- 240v irrespective of the constant voltage and current fluctuation, failure and instability.
        This project helps the society in many ways which include the stepping up and down of voltage in order to avoid destruction and at is used to vary the amount of power supply. It is a protection device.

CHAPTER ONE
1.0       INTRODUCTION
The design and construction of 1000VA automatic voltage regulation is made to solve the problems of fluctuation of current and voltage supplied in the various facilities in our environment. In rent years, the destruction in our electrical and electronic equipment caused due to the and unsteady current has lead many home or family homeless and also an expense.
        The introduction of an automatic voltage regulation act as an answer prayer for the protection of our equipment since it comes into existence. This device is made to vary the amount of current supplied through the supplier.  It also helps to smoothing the voltage to be used in our electrical and electronic devices.
        The automatic voltage regulator is a protective device that brings out a steady current which varies between 100V-240V.  This device is very good and active in terms of protecting our devices.
1.1    OBJECTIVE / AIM OF STUDY
The Automatic Voltage Regulator (1000VA) is made to produce a stable and steady current.  The device is produced or designed to perform the following functions which includes.
        This device is used to step up and step down the voltage when the supply is faulty. It is an appliance that helps to prevent the life span of electronic any electrical and electric devices that makes the use of it.
        It also brings out a filtered current which bring smothering the components that can make use of it.  This system can be called an automatic machine because it perform the functions of automatic system in which by changing from one stage to another in order to feet the valuable current and voltage to the supplied by the components to makes use of it.
        The damages received by the society which ignored the use of automatic voltage regulator is so complicated that it cannot be mentioned in this project. But my advice to the society is to try as much as possible to make the use of automatic voltage regulation in their electrical and electronic components because it is a protective device.
1.3       THE SCOPE OF THE STUDY
The design and construction of IkVA Automatic Voltage Regulator is the project we are construction.  We are working on this machine because we have some idea on how this machine can be constructed and also on how it works.  We are also doing this because we want to learn more abut it.
        As we have mentioned earlier, this device is a protective device that protects our electrical and electronic appliances out of current and voltage fluctuation. This is how it works.  When this system is plugged into the sucket or supply, it will receive a minimum voltage of 100v and filter the current and voltage thereby brings out suitable voltage output to be used by the devices in it.
        So, we are building or constructing this device to reduce risk and damages the fluctuation of current / voltage caused by power fluctuations.  
1.4    DEFINITION OF IMPORTANT TERMS
Fluctuation: The change of voltage from normal to low or
High.
Deep:                  Process of voltage and current to extent a long way down from its normal supply.
Unstable:            Not normal
