This document provides an overview and acknowledgements for a project on evaluating the performance of a three-phase power transformer. It begins by acknowledging guidance from teachers and professionals. The abstract then outlines that transformers play a vital role in power transmission and distribution by allowing voltage transformations, and that the project involved designing a three-phase transformer, testing an existing distribution transformer to measure parameters like resistance and losses, and evaluating the transformer's performance by comparing results to guaranteed specifications. It concludes by listing the document contents, which cover topics like hydropower plants, the DVC power grid, machine components, and transmission.

2. ACKNOWLEDGEMENT
CKNO
God gives us life to decorate it with Knowledge. Life without knowledge is like river without
water.
“AN ENGINEER WITHOUT A TECHNICAL TRAINING IS LIKE A SOLDIER
WITHOUT A WEAPON.”
It is my pleasant privilege to acknowledge my profound gratitude and indebtedness towards my
respected and learned teachers for their inspiration, constructive criticism and valuable
suggestions.
I want to thank particularly Mr. S.K. GUPTA (HR Manager- D.V.C, DHANBAD) and our
Training Coordinator for me an opportunity to work with such a prestigious organization.
I express my whole hearted thanks to Mr. HARSH SHRIVASTAV (Asst.Prof, Electrical
Engineering)
and Mr. NARENDR GOTHWAL (Asst.Prof, Electrical Engineering) for their
Sagacious efforts in accomplishment of this task.
Last but not the least I would like to extend my sincere thanks to the PHPS DHANBAD, for
answering my queries and clearing all doubts.

3. ABSTRACT
In the field of electricity, transformer plays a vital role and it is the Lifeline and integral part of
electrical transmission and distribution system. It is a simple static device operating on the
principle of electro-magnetic induction. Its function is to transform power at same frequency
from one part of the circuit to another.
The transformer is used as an important component in the power system for the following two
main reasons:
1. Minimize transmission and distribution losses by adoptingappro transmission and
distribution voltages.
2. To facilitate availability of power to individual consumers at voltages they desire for their
systems.
As a part of the project design of a three-phase transformer was done and its performance
evaluation was judged by comparing the results.
Testing was done on a three phase distribution transformer and the parameters like resistance, no
load loss, load loss, impedance voltages were measured, which were taken as input and the
efficiency at different loads and regulation at UPF and 0.8 PF were calculated.
The results thus obtained were compared with the guaranteed technical particulars and the
performance of the transformer was evaluated.
