• Oil also include in the insulating medium its
viscosity is requir always less in transformer
synthetic and mineral oil is used

De-moisture
In that industry there are
two ovens
1.fully automatic-90c
2.semi automatic-60c

15. Service of company

16. • Maintenance of transformer(repair)
14 August 2017 SITCOE,YADRAV 16
Faulty Transformer
Check continuity of winding
Removing faulty winding

17. • Oil Filtering-
14 August 2017 SITCOE,YADRAV 17
In warranty period of
transformer
maintenance free of
cost
Check the condition
of the consumer
transformer after 2
months

18. • Testing of oil-
14 August 2017 SITCOE,YADRAV 18
Oil Tester for Transformer Oil Breakdown Voltage Testing
Remove oil
Oil before and after filtering

19. Fabrication
14 August 2017 SITCOE,YADRAV 19
It is a lesser cutter it is used for the
cutting a cast iron sheet in
different shape
In that section welding the
different parts of
transformer like air fins,
conservator, valves etc.

21. Testing
14 August 2017 SITCOE,YADRAV 21
• Measurement of insulation resistance of H.V.&
L.V. windings .
• Voltage ratio measurement & check of polarities.
(Phase relationship/vector group).
• Winding resistance measurement .
• Magnetic balance test.
• No load loss & No load current measurement .
• Short circuit impedance & load loss measurement
• Di-electric value of oil .

22. •Dielectric test of oil
14 August 2017 SITCOE,YADRAV 22

23. Learning after training
• How to make main connection of transformer
winding
• How to find the fault in transformer ,how to
overcome
• How to filtering the transformer oil
• How to make H.V. & L.V. winding
14 August 2017 SITCOE,YADRAV 23

24. Conclusion
• We done this 15 days training we learn the how to
core assemble, how to turn the winding, when faults
come in transformer how to solve this fault.
• How to make the connection of winding, filtering
process of transformer oil and testing of transformer
