The project, so constructed is packaged in a plastic casing for
compatibility. On the surface of the package, there are three 100k
vol/pot which are used to demonstrate low voltage in a given phase.
Three amber LEDs represents the mains while the three blue LEDs are for
the Gen set. And these make up of the panel indicator.
1.2. OBJECTIVES OF THE PROJECT
One
of the objectives of this project is to design and construct an
automatic 3 – phase change – over with Gen set switching facility which
will automatically switch ON/OFF Gen set and change over between PHCN
and Gen set. It is also aimed at exposing the graduating student to
electronics system designing using random logic - especially in
designing in industries and power electronic. Another objective of this
study is to ground the graduating students in Engineering, scientific
and technical writing which is indispensable in their professional
practice.
1.3. SIGNIFICANCE OF THE PROJECT
This project work
signifies a lot in industrial automation and power electronics. It is
very useful in wood processing industries, oil rig equipments and other
manufacturing industries that used 3 – phase machines. A project of this
nature can be modified to function as automatic phase selector which
can be used anywhere.
1.4. SCOPE OF THE PROJECT
This project work
covers the following; transistor drivers, electromagnetic relay,
contractors, 3 – input AND gate encoder, shunt regulation and comparator
using Zener diode, delay/un-delay timer and other system.
