INTRODUCTION

1.1 BACKGROUND OF A 2.8KVA FUEL-LESS GENERATOR

This system of electricity generation is ecologically friendly, pollution free and sustainable. It can serve as one of the best alternatives to the unsteady power supply experienced in the country at large. This generator can be used in the hospitals, at schools, on work sites, data centres etc. It can also be built to the capacity of the required load.

1.2 PROBLEM STATEMENT

The adverse effect of the conventional sources of electrical energy on the environment together with carbon dioxide emission and cost of constant injection of fossil fuel have also been challenging. Hence there is the need for alternatives like fuel-less generator which can reduce to the barest minimum all the problems caused by power failure and thereby leading to maximum profit achieved.

1.3 AIM AND OBJECTIVES

The aim of this project is to construct a generator that will produce 2.8kva electrical energy constantly in order to take care of the unsteady power supply, while the objectives are as follows;

i. To construct a 2.8kva fuel-less generator.

ii. To show how electricity can be generated using DC motor as a prime mover.

iii. To evaluate the generator’s performance.

iv. To carry out reliability test and load test on the fuel-less generator in order to establish some of its characteristics.
