CE 2.2 Project Background
CE 2.2.1 Characteristics of the project
In this particular project, it mainly discusses about the design optimization technique for
single-phase power transformers using interactive PC-based computer program with the help of
MATLAB programming. However, in this project it also discussed about a procedure for the
proper illustration of the parameter variation impact on transformer design in terms of achieving
lowest production cost. Therefore, this paper also discusses about an efficient solution of power
transformer design by doing MATLAB programming. Along with the MATLAB programming, I
have also used PC-based interactive computer program which helps in doing better analysis and
design of single-phase transformers. In this project, I also implemented a mathematical model for
single-phase distribution transformer considering both copper and core losses. For the designing
of transformer in this project, it discussed about the design capacity increase by doing the proper
use of both windings (coils) and magnetic core. At the time of first designing work, all
specifications of transformer are determined and the magnetic data of 60Hz are transferred

through this power transformer. Moreover, in this project work, I also prepared the calculated
design result of transformer with the help of MATLAB and the implementation of PC-based
program in both shell type and core type transformer.
CE 2.2.2 Objectives developed for the project
With the purpose of developing this project successful and preparing the single phased
transformer with proper simulation more quantity energy needed to be transferred from one
electric circuit to other with the help of magnetic field and no changing frequency. Some of the
objectives based on this project work are listed below:
To understand the efficiency of different used electrical machines using negligible
amount of maintenance as well as supervision
To implement an efficient solution for doing designing work of power transformer with
the help of MATLAB programming.
To determine the size, efficiency, weight of an actual transformer and examination based
on this implemented project whether it can be used or not.
To do simulation and analysis of design performance by doing the proper use of PC-
based computer program with MATLAB as backend
To have the proper understanding of transformer tank for shell type transformer using
sand and coil pancakes.
To increase the power consumption load with the help of single phase transformer based
on some pre-determined constraints

CE 2.2.3 My area of work
As during this project work, I was already experienced enough in field work, I was
appointed as senior team leader. After resuming work in this project, my foremost work was to
understand all types of project specification and out goal based on that I also divided colleague
team mates based on their proficiency on each part. Moreover, as a senior team leader, I also
look after of all estimation and calculation work done by MATLAB as I personally is a
MATLAB expert. In this whole project work, I also formulated a proper framework based on
that all works will more forward and the determined goals can get achieved. Furthermore, I also
studied about the specification of all types of transformers based on that, tank transformer get
selected for this project work. In addition to this, I also calculated the design results of
transformer fabrication in all dimension of transformer. I also done the modelling of transformer
and also both Open-circuit test and Short-circuit test depending on different parameters.
CE 2.2.4 Project Group
ATL

In this project, we are 6 members along with project supervisor. I was appointed in this project as
a Senior Team Leader for leading 3 associate’s team with the support of an ATL.
CE 2.2.5 My responsibilities throughout the project
As a senior Team Leader, I maintained the responsibilities of doing different team
building work along with the resolving of all types of faced conflicts among the associates. I
always needed to be justified and fair with all associates so that their morale is always in positive
way. Along with this, as an electronics engineer, I had done various project related work also
like all types of complex calculations, simulation works and also setting an appropriate
methodology to gain the correct result. Apart from that, I had also taken part in the voltage work
also by noting down all the undergone wave forms based on input voltage, input current and
deduced output voltage. As a team leader, I was supposed to check all parts of work going on in
this project to have the clear idea of all requirements and whether it was going on right direction
or not.
CE 2.3 Distinctive Activity
CE 2.3.1 comprehending the theory of the project
Regarding the theoretical concept of this project, firstly, it discussed about the
specification of both frame and core. Depending on all these, it also discussed about the
transformer design work considering 25 KVA, 11000/433 V, 50 Hz and oil immersed natural
cooled distribution transformer. However, the most important work in this project was the
simulation of all waveforms from the continuous power supply. The results from both the
sinusoidal and square waveforms were calculated as per the below mentioned table:

In this project, the modelling of transformer was done from the alteration of both current
and voltage within the primary as well as secondary winding. The magnetized curve of
transformer is considered to be linear so that all calculation can be done by considering a simple
constant. After all the testing work, the performance parameter of interest was deduced after
solving the circuit design based on load conditions.
CE 2.3.2 Engineering knowledge and skills applied in the project
To complete this project, I had used the theoretical knowledge of transformer designing
along with the simulation techniques that done by MATLAB. In the methodology concept, I used
the knowledge of power consumption and voltage calculation depending on the circuit structure
of transformer. However, I used both the short circuit test as well as open circuit test. In addition
to this, the power also gets supplied in the transformer in both continuous and discontinuous
supply form. For the continuous supply, I used the sinusoidal waveform and square waveform on
other side, for the discontinuous supply, I used the square pulse waveform.

Figure 2: Square waveforms
I had also used the concept of PC-based programming for doing the designing work of
both single phase core type and single phase shell type transformers. Moreover, by using my
entire engineering concept, I made some assumptions that are considered in this project include:
a. The cores need to be proportioned due to which the flux density is uniform manner
b. The low voltage coil needs to be employed close to the core
c. The high voltage coil needs to be employed above the low voltage coil

Along with all these assumptions, another important factor for transformer design was resistance
per meter of both secondary and primary wires depending on a particular design temperature.
CE 2.3.3 Accomplishment and task performed
The most important task performed by me was the creation of the whole program flow chart
which is shown below:
Apart from the flow chart creation, I also accomplished the work of simulation based on
selected parameters and also successfully deduced the desired outcomes. As per the
responsibility of a team leader, I divided the whole works among all associates based on their

capabilities and also imitate the buddy concept among them so that they understand the proper
meaning of team work.
CE 2.3.4 Identified issues and their solutions
One of the major issues faced in this project was the selection of transformer type. Then
after the selection of core type transformer, I chose single phased transformer so that more output
can be gained from more input. In the single phased transformer, I faced problems from the
determination of wavelength. After all these core project problems, I also faced some difficulties
in the team work and their coordination. Secondly, another core problem faced in this project
discussed about the calculation of resistance per meter in wire table was calculated at different
temperature rather than the required temperature of the design work.
To overcome all these problems, I examined the input first properly so that the desired
results can be obtained. I also prepared different design alternatives in case of the failure of the
previous version. Apart from all that, I also did the efficiency comparisons in both core loss
ratio and efficiency parameters.
CE 2.3.5 Plan to produce creative and innovative work
In way to innovate the project, the calculation work is done from high and low voltage
coils, flux path length, peak flux and the calculation of RMS value of the magneto-motive force
and the mean length of flux path. I also used different team building skills and practices for the
creation of this best team. I used MATLAB in different innovate work of this particular project.
CE 2.3.6 Collaborative work
I had completed this project in a group work with my other colleagues who help in the
whole project work. I used to meet my project supervisor consistently and present a week after

week answer to him and spoke with him through calls and messages to talk about the data
expected to complete the task. I needed to core physics for the calculation work and also need to
acquire core programming knowledge to do the whole work of this project.
