CONSTRUCTION OF AUTOMATIC CHANGE OVER WITH GENERATOR TRIP OFF

ABSTRACT

As technological advancement has been on the increase in our society many have fallen in love with technology and world want to have a feel in virtually to every thing they do. A design has been made in combination of electrical and electronics to change over from one power sources to the other automatically and trip off generation after 40 seconds with out going through the point for manual operation. This project writing were organized in according way for easy understanding.

CHAPTER ONE

INTRODUCTION

BACKGROUND OF THE STUDY

This project is on the design and implementation of automatic change over and how it can be used to change from one power sources to the other automatically. The design comprises some arrangement that senses the power failure form either of the power sources and drives the electro mechanical switching device (relay) that is capable of changing two poles (live and neutral) to give out light or be on stand by to generator side.

As technological advancement has been on the increase in our society many have fallen in love with technology and wants to have a feel of modern technology in virtually to every thing they do. A design have been made in combination of electrical and electronics to change over from one power sources to the other automatically without many operation.

Electronic components such as relay transformer diodes were used thereby making the project less expensive for the implementation of the project and commercial application. Moreso the cost suitability and availability of the required components for the project circuitry were some of the major factors considered by the designer.

OBJECTIVES OF THE STUDY

To design a circuit that will automatically change over from main power supply (PHC) to power generating set and vice versa with the help of electro mechanically switching device that is being controlled by electronics component.

SCOPE/SIGNIFICANCE

This project design can be used to transfer power sources to the other automatically. The design could also be used in other application apart from changing power sources once there is a well though arrangement.

PROJECT REPORT ORGANIZATION

The project report has been organized into five chapters for orderliness and easy understanding of the information on the report design. Chapter one contains introduction design objectives/aim scope/significance of the report and report organization. Chapter two dealt on system component analysis literature review and theories/modules of design. Chapter three contains the system design description of the system building blocks system specification block diagram and the description of the overall operation of the system. Chapter four describes the implementation testing and results of the project. Chapter five finally dealt on the cost analysis calculation and recommendation for further improvement and ended with a page for references.
