CE 3.2 Project Background
CE 3.2.1 Characteristics of the project
The project of Design and Fabrication of Under Voltage and Over Voltage Protection
System was my first mini project in electrical and electronics engineering career. The on time
delayed circuit is not only responsible for protecting the loads from the switching surge but
even from the quicker changeover or the off or on effect. The inexpensive auto cut off circuit
is present here that is being fabricated with the help of the transistor and the other discrete
elements. This could be utilized for protecting the loads like television, refrigerator, and the
VCR from the undesirable over as well as under line voltages, and the surges that are caused
for the sudden failure or resumption of the major supply of power. This particular circuit
could be utilized directly as the standalone circuit within the main supply or the load, or this
might be inserted within an existing automatic or manual stabilizer or the load.
CE 3.2.2 Objectives developed for the project
This particular project of Design and Fabrication of Under Voltage and Over Voltage
Protection System consisted of various important objectives. They are given below:

 To design and fabricate under voltage protection system.
 To design and fabricate over voltage protection system.
CE 3.2.3 My area of work
The project of Design and Fabrication of Under Voltage and Over Voltage Protection
System was the third important project in my engineering career. I had several areas of work
in this particular project. My first major area of work was to provide technical support as well
as resolution when all the electrical problems were being encountered. My other area of work
involved researching about under voltage and over voltage and documenting the project
report properly. This project documentation was done by me perfectly.

CE 3.2.5 My responsibilities throughout the project
I had some of the major responsibilities in this particular project. The first and the
most important responsibility in this project was collaborating with the electrical engineers

and all other parties for identifying, defining and resolving the electrical technical issues or
problems. The test information regarding electrical equipments was analyzed and interpreted
by me. Moreover, I even planned for the electrical installations for minimizing waste of
materials and thus provided access for the future maintenance. The repair of the electrical
systems and the wiring including various other factors, however, not limited to the power
distribution systems, control panels, lighting systems, components of the machineries or
equipments, fire systems, security camera infrastructures and data wiring. The higher voltage
switching was performed by me and even generators were operators in support of the
operations at transmission plants. My other responsibilities were modelling, implementing
and complying with the electrical safety rules or related industry regulations.
CE 3.3 Distinctive Activity
CE 3.3.1 Engineering knowledge and skills applied in the project
I had applied some of the major skills in this particular project. The most important
skill that I have applied here to design the protection system of under voltage and over
voltage was assessment and improvement of electrical systems for the increased demand.
Moreover, I utilized my designing skills and knowledge in this project and hence the
protection system was made properly. Mechanical aptitude was the next significant applied
here. The intense knowledge of mechanics was required here for making the protection
system properly.
CE 3.3.3 Comprehending the Theory of Project
The protection circuit of under or over voltage with the time delay that was being
presented by us was the lower cost as well as the most reliable circuit to protect the
equipments from various damages. Whenever this line of power was switched over, it was
getting connected or linked to only appliance after the fixed time delay. This system tried for
