Abstract
Installing an electrical transformer can be difficult, particularly if you are not familiar with electrical transformers or if it’s your first attempt at installing one. Electrical transformers have to be installed with the utmost care and precaution to avoid internal damage of equipment. In the installation of the transformer 11Kva, we follow all the safety precautions and provide the required safety equipment. This transformer were installed according to ANSI/IEEE– and NEMA-approved regulations. In the process of this installation, we considered the voltage and frequency deviation with maximum efficiency and at moderate running and maintenance cost. A methodology for estimating an adequate transformer capacity with consideration of future expansion in load demand in the nearest future while the same transformer and other substation equipment will still be considered relevant and reliable. Advice on the best equipment and accessories to be used when constructing any distribution substation such as the one we worked on is also given, thus achieving a reliable supply of electricity within our society, which brings about socio-economic development
CHAPTER ONE
INTRODUCTION
Background of the study
This research shows its different chapters- the power transformer from many different aspects. The most important aspect covered by this research is the aspect of doing tests to the power transformer.
It is clear to us that the electricity network in Nigeria suffers from a lack of stability and continuous interruption of electricity, and this instability is because several reasons, some of these reasons related in general to the follow-up of the situation of transformers. That is why it important to discuss the various important tests conducted on the installation of transformers in Nigeria, and mention the other important tests that aren’t conducted in it, which will be recommended.
Objectives of the study
This study sought to examine the following:
- to show the practical steps involved in the installation of 11kva transformer system
- to examine the different components of transformer
- to determine the size of the required conductors (cables ), earth conductor, circuit breaker panel
Scope and Limitation of project
Many techniques and methods are utilized to fulfill the objectives of this research. These include field visits, collecting data from a transformer factory and from a transformer repair and maintenance service, monitor how the transformer tests are performed, and finally using MATLAM/SIMULINK program for simulate some of the tests.
