Schedule of Workshop

Details of the Workshop:

Preamble: Department of Electrical Engineering, CGPIT has organized two-day workshop on “High

Voltage Engineering” sponsored by Uka Tarsadia University. Total 133 participants

participated in this Workshop. The inauguration ceremony of Workshop was started by UTU

song followed by lamp lighting and prayer to seek the blessings of almighty. As per tradition

of CGPIT, all the dignitaries were given a warm welcome and were felicitated to express

respect and gratitude towards them for devoting their valuable time and gracing the

workshop. The dignitaries that graced the inauguration ceremony of workshop were Dr. N. C.

Shah (Director, CGPIT), Prof. V. K. Shah (Principle of Diwaliba Polytechnique), Ms. Purvi

Tandel (Head of CO/IT Department, CGPIT), Mr. Gunvant Solanki (Incharge Head of Civil

Engg. Department), Mr. Ankit Desai (Incharge Head of Mech./Auto Department), Prof.

Manish Sinha( Assistant Professor, EE Department, BVM Engineering College), Dr. Ritesh

Patel (Department of Electrical Engineering, G. H. Patel College of Engineering and

Technology). The dignitaries and expert were felicitated by the coordinators of the workshop.

Prof. Karmani Rajput gave a brief introduction about the workshop. She introduced the

experts and expressed her views about the importance of workshop. The H.O.D of electrical

department, Prof. Rakesh Gajre gave the welcome speech and gave an overview of the power

system and its importance in the industries.

The Honourable Director of CGPIT, Dr. N.C. Shah gave the welcome speech. He motivated

the students and faculties for participating in technical events like short term training

program, workshop, expert talk, etc. He also congratulated and appreciated the efforts made

by the Electrical department for organizing such workshop. He shared his knowledge about

the necessity of power system in industries in present scenario and its importance in their

career. Prof. Karmani Rajput gave the vote of thanks.

Session Detail: All the sessions were very interactive and laid a very good impact on the audience.

Session-1: Lightning and Overvoltage Protection

Session-2: DESIGN of HVDC Circuit

Session-3: Lab Session

Session-4: Condition Monitoring

Session-5: Partial Discharge in Electrical Equipment

Session-6: Lab Session

• Lightning and Overvoltage Protection

Dr. Ritesh Patel started with the basic concepts of power system and motivated students to

learn things in detail. He discussed Lightning mechanism, Effects of lightning on Power

system, Protection from Lightning, Shielding wires, Ground rods and Counterpoise,

Lightning Arrester, Surge Absorber, Insulation coordination in much detail. He also

showcased the importance of HVDC and requirement of the engineers in generating higher

voltages to compensate the requirement of the nation.

• DESIGN of HVDC Circuit

Prof. Manish Sinha focused on the advanced generation techniques of HVDC such as

utilising Voltage multiplier circuit, Marx generator and so on. He also discussed Designing

and simulation of HVDC circuit with detailed calculation. He also touched basics of impulse

voltage generator and stated it as a research area.

• Lab Session

In this session Mr. Jay Patel, Mr. Hiren Sidhpuria, Mr. Bhargav Patel, Mrs. Chand Thakor

conducted lab session in the labs using V-lab (Virtual Lab) and gave practical glimpse of the

titles covered in the theory.

• Condition Monitoring

In this session Mr. Chinmay Desai has discussed regarding how to find failure rate of the

machine and protecting those machines from heavy fault and frequent maintenance

requirement of machines like Induction Motor and Transformers.

• Partial Discharge in Electrical Equipment

In this session Mr. Jay Patel discussed basics of partial discharge in the static and rotating

machine and its impact on the cables and transmission line. He emphasised on the selection

and co-ordination of equipments for the least fault condition and best performance.

• Lab Session

In lab session, Mr. Jay Patel, Mr. Hiren Sidhpuria, Mr. Bhargav Patel, Mrs. Chand Thakor

showed practical experiments of High Voltage equipments starting from oil testing of

transformer to impulse generation. They started from the basic rules and safety measures

required in the lab. The demos were already prepared and participants were showed. And

then it was open for general discussion and questions.
