respectively.

In the process of forward integration and diversification product line, it began manufacturing of distribution

transformers & electronic energy meters in1997 & 2000 respectively.

With the growing trends in power sector the company also diversified itself in to engineering procurement

and construction(EPC) & exacting business for rural electrification of villages. export is another thrust area

for the company.

The Products are being regularly exported to the African& idle east countries to meet their ever expanding

infrastructure and power needs.

An installed capacity of 2500 MVA for transformers & 600000 no. of electronic energy meter meets our

customer requirements within a short span of time.

Annual turnover for year 2010-11 is $48 million and the endeavour is to touch US$67 million turnover for

year 2011-12.

ACKNOWLEDGEMENT

Many individual have proudly influenced me during my industrial training of B.TECH at MAHASHAKTI

ENERGY LIMITED, BATHINDA and it is pleasure to acknowledge their guidance and support. In

MAHASHAKTI, I learned many things, like, the project training is mainly aimed at enabling the student to

apply their theoretical knowledge to practical as "The theory is to know how and practical to do how" and to

appreciate the limitation of knowledge gained in the class room to practical situation and to appreciate the

importance of discipline, punctuality, team work, sense of responsibility, money, value of time, dignity of

labor. It was a very good and new experience of training because all the things I studied in books were totally

different in practical work.

I would like to express my gratitude towards Er. Ravi Sharma who took keen interest in my training, who

helped me in every possible way and is source of inspiration for all the group members.

MAIN PROJECT

My main project of training on which i am working is Transformer. As we know a transformer is a static

electrical device that transfers energy by inductive couplingbetween its winding circuits. A varying current

in the primary winding creates a varying magnetic flux in the transformer's core and thus a varying magnetic

flux through the secondary winding. This varying magnetic flux induces a varying electromotive force (emf)

orvoltage in the secondary winding.

Transformers range in size from thumbnail-sized units hidden inside microphones to units weighing

hundreds of tons interconnecting the power grid. A wide range of transformer designs are used in electronic

and electric power applications. Transformers are essential for the transmission, distribution, and utilization

ofelectrical energy.
