This document discusses a training seminar on transformers presented by Vishal Sen to Mr. Shantanu Kumar Sharma. It begins with an introduction of Friends Transformer Pvt. Ltd, a company that repairs and manufactures power transformers, including repairing 1000KVA transformers for the government of Ajmer. The document then discusses the basic components and principles of transformers, including their core, windings, bushings, oil filling, conservator, cooling tubes, breather, and explosion vent. It describes the manufacturing process of transformers and the assembly of their main parts. Finally, it lists the main machines used in transformer repairing, such as a heating chamber, winding machines, insulation resistance tester, oil filling and filtration machine

4. Friends Transformer Pvt.Ltd. Company
• This company was established in
the year 2011 for Repairing &
manufacturing power
transformer.
• This company repairs 1000Kva
Transformer.
• This company takes orders for
repairing government
transformers and the payment is
made from Ajmer by passing the
bill.

5. Introduction of Transformers
• Transformer is a static device, which
transfers electrical power from one
voltage level to another voltage level
with out changing the frequency.

6. Basic Principle

7. • Core
• Winding
• Bushings
• Oil filling in transformer
• Conservator
• Cooling tubes
• Breather
• Explosion vent
Manufacturing of Transformers
Assemble:-

8. Part of Transformer :
CORE:
The core is made of silicon steel to reduce eddy current loss.

9. Winding:
Part of Transformer:
LV Winding
HV Winding

10. Bushing:
Part of Transformer:
HV Bushing
LV Bushing

11. Oil filling in transformer:-
Part of Transformer:
• Transformer oil is poured
into it. This is called
Naphthenic Mineral Coil.
• A type of petroleum oil is
used in the transformer. It
does not catch fire quickly
and is a good conductor of
heat and a poor conductor
of electricity.

12. Conservator:
Part of Transformer:
• There is a tank of
a cylindrical
shape which is
attached to the
upper part with
the body of the
transformer.

13.  Cooling tubes are
used to cool the
transformer.
 Fans are used in large
transformers because
large transformers
heat up quickly.
Cooling tubes:-
Part of Transformer:

14. Breather :
Part of Transformer:
• The breather contains silica gel which
absorbs moisture

15. Part of transformer:
Explosion vent:

16.  Heating chamber
 HT/LT coil winding machine
 Insulation Resistance tester
 Oil filling & Oil filtration machine
 Transformer Turn Ratio meter:

18. HT/LT coil winding machine:
LT coil winding machine HT coil winding machine

19. Insulation Resistance tester/ Magger:-
• It is used to measure
the resistance of
insulation of
electrical equipment
such as cables,
transformer
windings, motor
windings etc.

20. Oil filling & Oil filtration machine:

21. • It is used to check
the winding of the
transformer and
also to check any
fault in the
winding.
