1.2. OBJECTIVES OF THE PROJECT
The
major objectives of this project is to design and construct an
automatic change-over switch with Gen set switching facility capable of
transferring control from MAINS to Gen set.
It is also aimed at
equipping the graduating student with Hands – on experiences which is
invaluable in their professional practice. It is aimed at grounding the
graduate of EEE in electronic system designs involving power control and
automation using random/Hard wired logic. Another objective of this
project is to acquaint the graduating students on the ethics of
Engineering, technical and scientific writing which is a nucleus of
engineering professional practice.
1.3. SIGNIFICANCE OF THE PROJECT
This
project work signifies a lot in Electrical power control and
automation. It means a lot in EEE. This project is a design that has to
be developed and funded for commercial purposes regarding its
usefulness. This project eliminates the stress, time delay and other
drawbacks in manually operated types. The project can be modified to
display the phase in use at a particular time using a single seven
segment Display and its appropriate circuitry. It also exposes the
students to digital system designs involving Encoders & Decoders.
1.4. SCOPE OF THE STUDY
This
project work focuses on the design and construction of automatic
change-over switch with Gen set switching facility. It covers the
following; Encoders and Decoders, Relays/Contactors, 3 – phase regulated
DC power supply unit, passive and active components, Generator
switching mechanism and it x-rays the mode of calculation of the basic
circuit parameter used in the design.
1.5. PROJECT REPORT ORGANIZATION
This project report is presented in six chapters to appropriately illustrate the steps involved in its implementation.
Chapter
One introduces the project overview, objectives and its significance.
Chapter Two is basically the literature review and some theories
relevant to the design. Chapter Three x–rays the methodology and
analysis while Chapter Four covers the system design and description.
Chapter Five elaborates on the implementation, testing and result.
Finally, Chapter Six is about the summary of the entire theories and
recommendation.

ABSRACT - [ Total Page(s): 1 ]This project work deals on the design and construction of an automatic power changeover that will change/transfer control from MAINS to Gen set and can switch ON/OFF the Gen automatically. The system integrates phase selector in MAINS and changeover to Gen. It is designed in several blocks all combined to from one functional unit. A +5v regulated DC power supply unit forms the first block whose output is fed to priority encoder and decoder block. The output of the BCD – Decimal decoder is ... Continue reading---
