PREFACE

There is a well-known saying “knowledge without application is a waste”. So it is very important

to provide with practical knowledge. It’s is easy to study the fundamental of engineering but it is

always difficult to implement them in engineering environment. No doubt classroom study is the

important part of knowledge of the engineering studies, but practical exposure provides some

extra knowledge about the theoretical concept. Instrumentation and control is rightly said to be

the life line of the industry. The large scale industrial production has resulted in widening the

area of instruments. The industry has to depend upon proper instruments and controlling actions

for taking various strategic decisions. Instrumentation and control provide necessary information

to the industry. This industry is made useful by analysis and interpretation of instruments with

the help of controlling elements. It helps industry in planning, co-ordination, communication and

controlling.

I have done my training at Northern Region Pipelines .During the training period I have learnt

about different type of instruments and its application. I have learnt about the automation of the

pipeline system using PLC and SCADA and about its controlling in the T & I Control room. This

report includes the comprehensive study of instruments and its controlling action.

ACKNOWLEDGEMENT

It was a matter of immense pleasure for me to undergo Industrial Training as a part of my

curriculum of B.Tech (Applied Electronics and Instrumentation Engineering) in a Public Unit

like Indian Oil Corporation Limited, Panipat.

I would like to thank Mr. S.K Gautam ,Senior Manager, T&D , NRPL, IOCL, PANIPAT for

giving me an opportunity to learn and experience the environment of IOCL. I would expressmy

sincere thanks to Mr. M.K. Dhiman, Chief Manager ( T&I ) & TSfor accepting me as vocational

trainee at IOCL PANIPAT pipeline. I also take the opportunity to thank Mr. Vinod Kumar,

Manager ( T&I ), who have provided me detailed information and extended full help during the

Training Period.

I would like to thank Ms. Neha Singh,T&I E and Mr. Suresh Kumar , SO & ME, for their

valuable guidance and giving their precious time for giving me valuable information on different

machines being used in NRPL and taking us for field work.

Finally, I would like to express my thanks to all members of IOCL, for accepting me as a

Vocational Trainee in such esteemed organization.
